Go Native! A Jailbreak Tweak that Adds Multitasking to Your Outdated Apps

By now, there's absolutely no excuse for an app not to support Fast App Switching, the iPhone's form of multitasking. It's been about six months since iOS 4 appeared on the scene, an update in which we finally received native multitasking on our iPhones.

Understandably, not all of our apps flew out of the gate with multitasking support built in; slowly but surely, they were updated to add support for such a critical feature. Sadly, there remain apps that have been neglected; apps that have yet to taste the sweet nectar of multitasking.

This is where jailbreaking comes in handy. Jailbreak apps like Backgrounder have provided an incredible workaround for these neglected apps. Go Native! adds yet another option to the playing field, but can it compete with Backgrounder?

How to Downgrade iPhone iOS 4.2.1

Let's say you recently updated your iPhone to iOS 4.2.1 and for various possible reasons, you are already regretting this move. It is possible to downgrade your iPhone 4.2.1 to a previous iOS, but for this, you need to have your SHSH blobs on file for the iOS you want to downgrade to.

To be completely clear, if you don't have your SHSH blobs on file for the iOS you want to downgrade to, you will not be able to downgrade. There is no way around that. This being said, here is how to downgrade iPhone iOS 4.2.1 to  4.1, 4.0.2, 4.0.1, or 4.0...

Will You Upgrade Your iPhone to iOS 4.1?

This week Apple will release the iOS version 4.1 for the iPhone. If our calculations are correct the newest version of the mobile operating system will be hitting iTunes on Wednesday, September 8th.

The last couple of updates from Apple haven't been anything to write home about. Version 4.0.1 simply addressed the algorithm while the antenna issue was flooding the news wire. After that, version 4.0.2 basically just patched up a security issue that Apple left exposed. As far as actual tangible features both refreshes were pretty dull at best...

How to Downgrade Your iPhone 4.0.2 to 4.0.1 Without SHSH Blobs on File

We've already gone over methods for downgrading an iPhone from iOS 4.0.2 to 4.0.1. Unfortunately, this method requires you to have your SHSH blobs on file on Saurik's server, which some of you don't have.

There is a post today on the Big Boss blog about how to downgrade from 4.0.2 to 4.0.1 without SHSH blobs, so I thought it might be helful to some of you.

How to Downgrade iPhone 4.0.2 to 4.0.1

This step by step guide will show you how to downgrade your iPhone iOS 4.0.2 to iOS 4.0.1. These steps are pretty simple but there is one major requirement: you must have your SHSH files saved on Saurik's server. There is absolutely no way around it. If you don't have your SHSH, you won't be able to downgrade your iPhone.

In this tutorial, we will see how to downgrade the iPhone from 4.0.2 to 4.0.1 but the steps are the same if you want to downgrade to iOS 4 or even 3.1.3.

There are several methods used to downgrade the iPhone. We will learn the method that uses TinyUmbrella. No file editing will be necessary.

How to Downgrade from iOS 4.0.2 to 4.0.1

Step 1: Let's download your SHSH blobs from Saurik's server to your computer. To do so, download TinyUmbrella and plug your iPhone in. Select the "Advanced Options" box. Also select the firmware version to which you wish to downgrade. Finally, select "Cydia" under "Request From". Then hit "Save My SHSH". This will grab your SHSH files from Saurik's servers and save them on your computer.

Step 2: Download the firmware to which you wish to downgrade to from our iPhone downloads section. Save it to your desktop.

Step 3: Put your iPhone in DFU Mode. To do so, launch iTunes and plug your iPhone in. Press and hold the Home and Power button together for 10 seconds. After 10 seconds, release the Power button while still holding the Home button until iTunes pops up and says it has found an iPhone in recovery Mode.

Step 4: Run TinyUmbrellaand click the "Display SHSHs" button to make sure your SHSH blobs were downloaded to your computer. Once done, click "Start TSS Server".

Step 5: Now we're going to restore to the firmware you want. To do so, launch iTunes and plug your iPhone in. Hold to SHIFT key (Windows only) or ALT/Option key (Mac only) while clicking on Restore. Make sure you hold the key while clicking Restore. A window will open. Simply select the firmware you downloaded in step 2.

Step 6: Your iPhone will start the restore process. You will most likely get several errors (error 1011, 1013, and 1015) but that's ok, don't worry about those.

Step 7: Finally, we need to get your iPhone out of recovery mode. To do so, simply click "Kick Device Out of Recovery" in TinyUmbrella.


You should now be back on a previous iOS, giving you the ability to jailbreak and unlock.

How to Jailbreak iPhone 3G iOS 4.0.1 with RedSn0w

iOS 4.0.1 for iPhone was released a few hours ago and those of you who have an iPhone 3G are already able to update and jailbreak iOS 4.0.1 using RedSn0w 0.9.5b5-5. Note that RedSn0w will jailbreak the iPhone 3G only. At this time, there is no jailbreak for other devices on iOS 4.0.1, which is why you should not update if you rely on your jailbreak.

Instructions to jailbreak your iPhone iOS 4.0.1 with RedSn0w remain the same except you must update to iOS 4.0.1 and point RedSn0w at the 4.0 IPSW even though you're at 4.0.1.

The Dev Team and Comex are expected to release an update to Spirit sometimes soon. This new version of Spirit will most likely jailbreak all devices on 4.0.1.
