iOS 5.0.1 Untethered Jailbreak for pre-A5 devices released: RedSn0w

If you have been following the development on the iOS jailbreak community, you would probably know by now that the untethered jailbreak has been released for iOS 5.0.1 for all iDevices (except for iPhone 4s and iPad 2). Few hours right after the release announcement, I jumped in immediately to restore my iPhone 4 (which was on iOS 4.3.2) and jailbreak it. Dev-team has release the latest RedSn0w tool (version 0.9.10b2) that includes the exploit to jailbreak the iOS 5.0.1.

There are some pre-requisites before you try and jailbreak your iDevice. Click on for more...

Transition from iOS 4.x to iOS 5 and Jailbreaking

I have recently made a transition from iOS 4.x to iOS 5 on my iPhone 3GS and I can say it wasn't a particularly smooth sailing journey. Of course we're talking about jailbreaking it as well. My plan was to do this:

1. Sync & backup iPhone 3GS with iTunes
2. Fully restore iPhone to iOS 5
3. Jailbreak iOS 5 with redsn0w
4. Install AppSync 5.0+ from Cydia
5. Restore from backup to iPhone with iTunes.

Sounds easy right? Wrong! Now usually when after I sync and backup the iPhone before an upgrade of the firmware, I will do a backup of the backup first so I can do it again if I screw it up. I have written an article on how to do this before and you can see it here: [Restoring from a backup for iPhone, jailbreak or not!]

redsn0w untethered Jailbreak for iOS 4.3.1 on the iPhone & iPad

I'm always asked this question by my friends, "Hey dude, is the iPhone iOS 4.3.1 jailbreak out yet?" ever since iOS 4.3 was released. Finally, the Dev-team have released the latest jailbreak for the iOS 4.3.1. What more.... it is an untethered jailbreak. The tethered jailbreak was released earlier but I would always refrain people from using it. Imagine you are out and either your battery drained or you need to reboot your iPhone after a Cydia app installation or you have a non-responding phone which needed a hard boot? With a tethered jailbreak, you'll be running around like a headless chicken.

Jailbreak iPhone iOS 4.2.1 with Greenpois0n RC5 without restoring

Finally, if any of you that have been camping out waiting for an untethered jailbreak for your iPhone on iOS 4.2.1, the wait is finally over. The iPhone 3GS with new bootroms and the iPhone 4 only had a tethered jailbreak using the RedSn0w tool up until now. I have since been using RedSn0w 0.9.6 RC8 and have been in tethered hell. Every reboot whenever without any PCs (or Mac) around would be devastating! Any updating of Cydia apps that requires a reboot and you better have RedSn0w at hand... But Greenpois0n RC5 has finally been released and it is an untethered jailbreak solution.
