If you load up Cydia today you will notice that it is now showing your SHSH blob for iOS 4.2.1. It's probably due to the recent release of RedSn0w 0.9.6b7, the long-awaited but complicated untethered jailbreak for iOS 4.2.1.
If you don't see your 4.2.1 blobs in Cydia, maybe you should use TinyUmbrella and make sure you're 100% ready for any eventuality.
The Dev Team has released their Redsn0w beta, dubbed Redsn0w 0.9.7b1 for iOS 4.2. We wanted to alert our readers, and at the same time provide a word of caution about the beta release.
To quote the Dev Team "This is a beta tester program. It’s not a general release!  Things can go very wrong, so please don’t even consider testing if you have pictures or other media on your device that you haven’t backed up!"
For that reason we recommend you hold off until the official release, especially if you rely on an ultrasn0w carrier unlock...
Even though Comex said he wasn't sure he was going to be able to meet his Christmas deadline for an untethered jailbreak, it does seem we'll get a nice gift from the Dev Team after all. According to the Team's blog, an updated version of RedSn0w that implements a "backup plan" will be released and will deliver an untethered jailbreak for iOS 4.2.1.
Things seem to be rushed a bit as the Dev Team is looking for beta testers to run this RedSn0w untethered jailbreak and make sure every bug is taken care of before the public release...
Did MuscleNerd spoke too fast when he said last week that we'd get an untethered jailbreak for Christmas? It sure looks like it when reading this tweet Comex sent out a few minutes ago saying that he was going to miss his Christmas deadline..
At this point, I'm not sure whether Comex is working on an untethered solution or a full new jailbreak tool (jailbreakme?) One thing is sure though, we might not get anything from him this Christmas...
The iPhone 4's gyroscope is one of the more underused features of Apple's flagship iOS device, so it's nice to see developers like Occipital -- creator of the iPhone app 360 Panorama -- put the technology to good use.
During the development of 360 Panorama, the crew uncovered the ability to control Mobile Safari using nothing more than the iPhone's gyroscope. Want to give it a test spin? Check out the link inside...
If you decided to update to iOS 4.2.1 and jailbreak using RedSn0w, you most likely have a tethered jailbreak, which requires you to plug your iPhone in and kickstart it with RedSn0w every time you reboot. Very inconvenient.
We've had words for a while that the Dev Team was working on an untethered jailbreak, which MuscleNerd confirmed would be available before Christmas.
Today, the Dev Team's frontman gave us more information about this untethered jailbreak via a tweet in reply to someone asking if we'll have to fully restore the iPhone and run RedSn0w again in order to benefit from all the untethered goodness...
Last month the Dev Team released an update to their UltraSn0w tool which allowed to unlock the iPhone 3G and 3GS loaded with the latest iOS 4.2.1. The iPhone 4 was left out of the equation and unless you're still on baseband 01.59.00, you can't unlock this device yet.
Today, some good news was uncovered about an unlock for the iPhone 4 iOS 4.2.1 baseband 02.10.04 in a tweet sent out by Sherif Hashim. The iPhone hacker confirmed that an unlock for 02.10.04 will be available, most likely before January 16th...
Earlier this month, iPhone hacker Comex mentioned on Twitter that an untethered jailbreak would be available before Christmas. It's been over a week now and we hadn't had any status update until MuscleNerd confirmed the release of an untethered jailbreak to be released before Christmas.
Minutes after tweeting the above info, MuscleNerd deleted this tweet, which is nowhere to be found now. So why did he do this?
PkgBackup is one of the more expensive jailbreak apps that you will find on the Cydia, but you'd be hard pressed to find a developer that's put as much continuous work into their app.
The backup solution has been on the receiving end of quite a few updates recently, so I thought it would be appropriate to visit some of PkgBackup's most convenient features.
One of those features is the wonderful DropBox integration, which is so good it inspired me to write this love letter...
By now, there's virtually a million and one ways to adjust the brightness levels on your iPhone, so is there really a need for yet another way to address the issue?
While there may be other alternatives, few are as quick and simple to use as Light Bright. The developers claim it's the easiest way to adjust the brightness on your iPhone, but is purchasing this tweak a bright idea?
Apple seems to have finally realized that brightness controls are something that end users want quick access too, as evident by their inclusion of multitask bar brightness controls in iOS 4.2 for the iPad. Sadly, there just wasn't enough screen real estate on the iPhone to do something similar...
According to certain device management vendors, Apple, without an explanation of any kind, has dropped its own jailbreak detection API from iOS no less than six months after releasing it. The reasons behind this decision are a mystery, as Apple has declined to comment on the decision to abandon the API in the release of iOS 4.2.1.
Apple's API let MDM (Master Data Management) applications access core information about the version of iOS running on any given device. Basically, the jailbreak detection API allowed certain applications to ask an iOS system if it had been compromised. Surprisingly, in the newly released iOS 4.2.1, that API is nowhere to be seen...
Have you ever wanted to know the file size of an App Store app update? Me neither, but apparently, some people do.
Introducing the methodically named AppStore Update Size, a jailbreak tweak for all of you app weight watchers out there.
