iOS 4 Installed On 50% of iPhones

A recent survey by online ad network Chitika reveals that 50% of iPhones are now running iOS 4. iOS 3 is installed on 49% of iPhones, while the 1% remaining still runs the older iOS 2.
Looking more deeply, iOS 4.0 – the version released on June 21st – is the dominant single version at 44.5%. Version 4.0.1 – the latest official release for the iPhone 3G, 3GS and iPhone 4 – clocks in at only 5% of the market, not surprising given that it was released less than a week ago.
Seeing how slow iOS 4 can make your iPhone 3G, I understand why that many people didn’t update. Another reason might be that people want to keep their jailbreak. I’d be curious to know if iOS 4 adoption goes up once Spirit is released sometimes in the next few days.

What iOS version are you running on your iPhone?

Parody: iOS 4 on iPhone 3G

Sad, but true… This is what iOS 4 looked like on the couple iPhone 3G I saw it running on.

If you have an iPhone 3G with iOS 4, please tell us if you’re iPhone is still as snappy as ever or if it slowed down.

When Will the Next iOS 4 Update Come Out?

Following the antenna issue fiasco, Apple issued an official statement in which it said it would release an update to iOS 4 “within a few weeks”. What does a few weeks mean? 2? 3? 10? No one knows for sure.

We can still try to figure out when this update might come out by looking at the past updates of iPhone OS 1, 2, and 3. That’s what tiPb did and here is what they found out:
Neither iOS 1.0 nor 2.0 nor 3.0 were bug-free and while it’s easy to forget, users were clamoring for fixes almost as much in years past as they are now. That said, iOS (iPhone) 3.0.1 was released July 31, 2009. 2.0.1 was August 4, 2008. 1.0.1 was was July 31, 2007.
Looking at this past update pattern, one might assume that iOS 54 will get an update in the next 3-4 weeks, however, Apple might be delaying this update in order to work on patching the holes of the exploit found by the Dev Team and Comex. That’s what I, and many others think anyways. Time only will tell.

When do you think iOS 4 will be updated?

Spirit Jailbreak for Every iPhone iOS 4 on Its Way

Yesterday I was telling you the  Dev Team is working hard on an unlock for iPhone 4. Some of you may have wondered why the Dev Team would be working on an unlock when a jailbreak is not even ready yet, right?

That’s because according to MuscleNerd, a jailbreak for all devices at iOS 4 is already taken care of by the upcoming release of Spirit by Comex.

Now the question is: when will Spirit for iOS 4 be available? With Apple supposed to release an update to iOS 4 in the upcoming weeks to supposedly fix the antenna issue, I doubt Comex will release Spirit beforehand and give Apple a chance to patch the exploit.

I bet you can’t wait for Spirit for iOS 4, can you?

How to Fix iOS 4 Exchange Sync Problems

After updating to iOS 4, you might have encountered issues when syncing your Microsoft Exchange account. I know I did. Immediately after setting up Google Sync on my iPhone iOS 4, the sync took forever to complete. I ended up deleting and adding the account several times but it didn’t really fix the issue as it would still take forever to sync new contacts or new events in the calendar.

According to this Apple Support ticket, I am not the only one. Here are the symptoms: immediately after updating to iOS 4, some users may notice that Exchange ActiveSync Mail, Contacts, or Calendars do not sync, or sync very slowly. In addition, some Exchange Server administrators may notice their servers running slowly.

Here is the fix offered by Apple:

To work around this issue, users should install a configuration profile from Apple that increases the amount of time the iOS 4 device will wait for the Exchange Server to respond to its sync requests. For best results, the profile should be installed on as many iOS 4 devices at your company as possible.

To install the profile:

Use Safari on your iOS 4 device to download the configuration profile. It may be easiest to read this article with your iPhone or iPod touch and tap the download link there, but you may also email the attachment to another email account on your iOS 4 device, and tap the attachment to open it.
Tap Install to install the profile, and enter your passcode if prompted.
A warning message will appear because the profile is not signed. Tap Install Now.
Tap Done to complete the installation, then power off your device and power it back on.
Wait for your Exchange data to finish syncing.

After installation, the profile will be listed under Settings > General > Profile.

Have you had this issue? If so, did this fix work for you?

iPhone 4 Jailbreak: What, Why, and When?

What
The act of “jailbreaking” your iOS device simply means enabling otherwise disabled features and gives you the ability to add applications that aren’t in Apple’s notorious App Store.  For example jailbreaking your device prior to iOS 4 was the only way to run multiple applications, like Pandora, at a time.

The jailbreaking community is the largest phone/hacking network on the net with 100s of blogs receiving millions of hits from users looking for the latest news in customizing their iPhone iPod Touch, and now iPad. Saurik, author of Cydia, the most popular alternative to Apple’s App Store, reports that Cydia receives over 2 million unique hits per month.
Why
So now that you know what jailbreaking is, let me tell you why the heck you’d want to do it! I know what you’re thinking. “Cody I just got the new iPhone 4, it already comes with multitasking, and I have access to 250,000 sweet apps in the App Store, why would I wanna jailbreak my iPhone?” Easy.

Those of us who are still hungry to free our iDevices have many reasons. I myself, as written before, am crazy about SBSettings. It’s an application that gives you an unobtrusive, drop down widget menu that enables you to turn airplane/bluetooth/wifi on and off with 1 touch. And because it’s only available in Cydia, your device must be jailbroken in order to obtain it.

Other popular applications include Winterboard, an app that enables you to completely customize the look of your iDevice, emulator to play NES games, and MyWi that turns your iPhone into a wireless hotspot.

Unlocking is also a common reason people jailbreak their devices. Unlocking means removing the carrier lock on the phone to enable it to work with a different network. For example, unlocking your iPhone and activating it on T-mobile’s network due to coverage or cost reasons.

Of course an iPhone can only be unlocked to a network with the same chip technology, in the States it’s GSM. Anyways if you haven’t picked up on the theme of the article, your iPhone has to be jailbroken to be unlocked.

There are some cool reasons to jailbreak, but it sounds really complicated. Wrong again! What started off as a complicated, combination of software/hardware hacks, has become almost as easy as plugging your iDevice into your computer, and running a simple application.

Thanks to hackers like The Dev Team and GeoHot, the jailbreaking process has become extremely easy. Although you always run the risk of causing damage to your device, and possibly voiding your warranty, most people jailbreak without problems.
When
Ok, so your sold on jailbreaking your shiny new iPhone 4 like a drunk man on another drink, what do you do now? Well, nothing for the moment. If you are looking to really customize your new iPhone 4 icons and lock screen, and get access to all of the above-mentioned apps, stay tuned.

There is a jailbreak for the iPhone 4 but it hasn’t been released to the public yet because it contains some of Apple’s proprietary code. But we should not have to wait too long, The Dev Team is usually pretty quick to respond to Apple updates.

If that doesn’t satisfy you, George Hotz aka GeoHot was heard talking about an exploitable bootrom that will enable an iPhone 4 jailbreak at a French underground hackers conference. So check back here frequently as we will obviously have full coverage including tutorials and how to guides.

Who out there has an iPhone 4 and can’t wait to jailbreak that sucka?

How to Downgrade Your iPhone From iOS 4 to 3.1.3

Every time Apple releases a new firmware, they stop signing the older one, which means you technically can’t downgrade to a previous firmware by restoring. Fortunately, if you have your ECID SHSH on file on Saurik’s servers, then you might be able to downgrade your iPhone from iOS 4 to 3.1.3 or earlier.

The trick is to make iTunes believe it is requesting a signature from Apple’s servers while it will actually be talking to Saurik’s servers.

Downgrading from iOS 4 to 3.1.3 does require you saved your SHSH on Saurik’s servers. If you haven’t, then you can’t downgrade.
Downgrade from iPhone iOS 4 to firmware 3.1.3
Step 1 for Windows: Make sure you are logged in with administrator privileges. Launch Notepad and navigate to C:/Windows/System32/drivers/etc. Add the following at the very bottom of the file: 74.208.10.249    gs.apple.com

Now save the file back where you found it.

Step 1 for Mac: In Finder, select Go To Folder, and enter /etc. Search the hosts file and right click on it to open with TextEdit. Add the following at the very bottom of the file: 74.208.10.249    gs.apple.com

Click Save As to save the edited file on your desktop. Name the file hosts, and make sure to uncheck the box that says “if no extension is provide, use .txt”.

Now drag and drop this edited file to /etc.

Step 2: Download the firmware you want to downgrade to from here.

Step 3: Put your iPhone in DFU mode. Launch iTunes and plug your iPhone in. Press and hold the home and and sleep button together for 10 seconds. After exactly 10 seconds, release the sleep button while still holding the home button. Keep holding the home button until iTunes tells you it has found an iPhone in recovery mode.

Step 4: Now hold the Option key (Mac only) or Shift key (Windows only) while clicking the Restore button in iTunes. A dialog box will pop up and you’ll be able to choose the firmware you downloaded in step 2.

Step 5: At this point, some of you will be fine. The iPhone will restore without any problem. However, some of you might end up in recovery mode again. It’s ok. We just need to kick the iPhone out of recovery mode. To do so, download and launch iReb for Windows or iRecovery (both Mac and Windows).

Welcome back to 3.1.3!

Tutorial: How to Jailbreak iPhone iOS 4 With PwnageTool

The Dev Team just released the latest version of PwnageTool to jailbreak iOS 4. There are many requirements that your iPhone must fulfill in order to be jailbreakable with PwnageTool and you should make sure to read this before going ahead with the jailbreak process.

Let me make this clear, READ THIS before going any further in the jailbreak process. Your iPhone might not be eligible for a jailbreak.

Now that we have the “warning” out of the way, jailbreaking your iPhone iOS 4 with PwnageTool is fairly easy and straightforward. PwnageTool is a Mac only tool that is used to jailbreak while preserving the baseband to make sure you can unlock if necessary at a further date.

This step by step guide and tutorial will show you how to jailbreak your iPhone iOS 4 using PwnageTool.

Step 1: Download the latest version of PwnageTool from our iPhone downloads section. You will need a torrent downloader (ie. uTorrent) to download the file.

Step 2: Make sure iTunes is up to date (currently version 9.2). If not, update iTunes and reboot your computer.

Step 3: Sync and backup your iPhone in iTunes.

Step 4: Download the latest iOS 4 firmware from here for your specific device.

Step 5: Launch PwnageTool and select your iPhone.

Step 6: PwnageTool will automatically detect your firmware. Click on the blue arrow to continue.

Step 7: PwnageTool will now ask if you have an iPhone contract that you would normally activate with iTunes. Choose YES if you have a contract with an official carrier (ie. AT&T in the US) and you don’t care about unlocking your device. Click NO if you don’t have a contract with an official carrier and want to unlock your iPhone.

Step 8: PwnageTool will now create the custom IPSW.

Step 9: When done, you will see the “iHaz success” message.

Step 10: Now that you have your custom cooked firmware, you need to install this firmware on your iPhone. To do so, plug your iPhone in iTunes. Once iTunes has recognized your iPhone, hold the “Alt/Option” key and click “Restore” at the same time. DO NOT click “Restore” without holding the “Alt/Option” key! A dialog box will pop up and you’ll be able to choose the custom IPSW file you created.

Step 11: PwnageTool will now install your cooked iOS 4 firmware on your iPhone. This process might take a few minutes so be patient. When done, your iPhone will reboot.

You’re done!

Additionally, make sure to check out these instructions if you need to unlock your iPhone.

UPDATE: This post is slightly outdated. Check out this page for the latest jailbreak information.

PwnageTool Jailbreak for iOS 4 Now Available

The Dev Team just updated PwnageTool to be compatible with iOS 4. PwnageTool is a Mac only solution for jailbreaking your iPhone while preserving your baseband, making the unlock process possible, or at least easier.

Now there are a lot of information to digest. PwnageTool will not work with all firmwares for every device. There are many restriction.

I invite you to carefully read this information provided by the Dev Team. Read it over and over again and see if PwnageTool will work for you or not.
Each supported device has few different scenarios that users need to consider when performing the upgrades, you need to check below and perform the upgrade in the particular way that matches your current device state.

NB: With PwnageTool 4.0 certain devices are not supported this is because they are not supported in iOS 4.0 or they are not supported by our software.  We’re working on ways to get past these restrictions.

iPhone 2G  – not supported
iPod Touch – not supported
iPod Touch 3G – not supported

iPhone 3GS

Summary: Currently, PwnageTool only works on previously jailbroken 3GS devices with the old bootrom.

If you have a Jailbroken iPhone 3GS with the OLD BOOTROM and you DID NOT use Spirit to jailbreak then you can create the ipsw with PwnageTool 4.0 and restore with your jailbroken recovery mode.
If you have an iPhone 3GS with the NEW BOOTROM this is NOT supported by PwnageTool 4.0

iPhone 3G

If you have a Jailbroken iPhone 3G at 3.1.2 (but not jailbroken with Spirit) then you should create the ipsw with PwnageTool 4.0 and restore from recovery mode or DFU mode.
If you have an out of the box iPhone 3G you should restore using a PwnageTool 4.0 ipsw using DFU mode.
If you have a Jailbroken 3.1.3 iPhone 3G it is very possible that this can fail from recovery mode, if this failure happens you will need to restore using DFU mode.
As an alternative to PwnageTool, you can use redsn0w on iPhone 3G (on both Windows and Mac) as mentioned in our last post.

IMPORTANT! Whenever you need to enter DFU mode, you will need to do so using PwnageTool.

iPod touch 2G

If you have an iPod touch 2G (non-MC model) that is jailbroken (but not with Spirit) then you can restore using recovery mode.
As an alternative to PwnageTool, you can use redsn0w on non-MC iPod Touch 2G (on both Windows and Mac) as mentioned in our last post.

Baseband Unlock

iPhone 3G and 3GS baseband unlockers (those who rely on ultrasn0w to make phone calls) should always be very wary to update their firmware, however our Ultrasn0w application will unlock all recent (including the current) 3GS and 3G baseband firmware versions.  Once you are jailbroken using PwnageTool 4.0, install ultrasn0w from Cydia and you’ll be unlocked.

Remember! This baseband unlock situation is rare, should you upgrade your iPhone blindly at the next iOS release please don’t expect an unlock – but for now you are OK (whatever state your baseband is in).

Let me remind you that if you have an iPhone 3G, you can jailbreak using RedSn0w.

If you have any question, please feel free to leave a comment.

The Ultimate Guides to iOS 4

iOS 4 was released yesterday and comes with over 100 new features. If you haven’t updated your iPhone yet, you may want to consider it so you can take advantage of all these new features.

I started writing a guide of all these new features, shortcuts and settings but I quickly realized that many other blogs before me had already created such comprehensive guides. Instead of trying to reinvent the wheel, I figured it’d be easier to direct you to these guides.

So I found two good guides that I want to recommend you to check out:

Gizmodo’s complete guide to using iOS 4
LifeHacker’s new iOS 4 shortcuts, features and settings your need to know

These 2 websites will show you the most exciting features of iOS 4.

iOS 4 Now Available for Download

The long-expected iOS 4 is now out and available for download. Depending on where you are in the world, it might not be available in iTunes yet. For those of you who can’t update via iTunes, here are the direct download links (also available in our iPhone downloads section):

iPod Touch 2G
iPod Touch 3G
iPhone 3G
iPhone 3GS
iPhone 4

Before upgrading to iOS 4, make sure you weight the pros and cons of iOS 4, but most importantly, make sure your iPhone is ready for iOS 4. As usual when a new firmware comes out, jailbreakers should beware.
