Semi-tethered jailbreak for iOS 5

iOS 5 has already been jailbroken to allow running on unofficial 3rd party apps, but the current jailbreak with Redsn0w is considered a “tethered” jailbreak because it requires that the phone be tethered and re-jailbroken any time your jailbroken iPhone, iPad or iTouch is rebooted.

We still await someone clever enough to create a fully untethered jailbreak of iOS 5, but in the meantime, there is “Semi-Tether” a semi-tethered jailbreak available from Cydia, one of the premier app stores for jailbroken devices.  Unfortunately, some apps won’t work after a reboot, but at least most of them well. For more info, check out App Advice’s article on SemiTether.

Tethered Jailbreak for iOS 5 on iPhone 4, 3gs, iPad and iTouch with RedSn0w

Those amazing iOS hackers have done it again!  iOS 5 has only been out a few weeks, but there is already a tethered jailbreak for all but the very latest hardware supported by iOS 5.  That’s right, your iPhone 3gs, iPhone 4, iPad, and recent models of the iPod Touch can run a jailbroken iOS 5.  I expect soon we’ll see the iPhone 4s supported too.  What’s more, there are already a jailbreak for the still-in-beta iOS 5.0.1.

If you are ready to dive in yourself, it’s best to go to the source and download the Windows or Mac versions of redsn0w 0.9.9b7.

Redsn0w succumbs to Greenp0ison: Untethered Jailbreak for all iOS 4.2.1

iOS 4.3 is due any day now, but the bigger news is that there is an untethered jailbreak available for recent devices running iOS 4.2.1.  The original jailbreak was redsn0w from the iPhone dev team. It was joined by Greenp0ison, but both had the same limitation, when jailbreaking recent devices, you had to hook it up to a computer every time your device was restarted.  Only iPhone 3gs and iPhone 3 users got the benefit of an untethered jailbreak. That changed last week.

An update to Greenp0ison is available that allows untethered jailbreaking of all current devices (which doesn’t yet include the verizon iPhone) from a Windows, Mac system.  No Linux yet, but hopefully it is coming soon.

iPhone 3.1 Out, Don’t Let it Re-Lock your Unlocked iPhone

Apple released an update to the iPhone OS today.  The 3.1 iPhone update brings lots of little improvements.  Don’t let iTunes tempt you with them if you have an unlocked iPhone.  The new firmware will upgrade your baseband firmware, relocking your iPhone and, potentially, making it impossible to unlock again.

The good news is that your iPhone can still have that 3.1 iPhonee goodness and your unlocked iPhone.  You just need to trust in the iPhone Dev team, because their tools provide a way to install the update without updating the baseband and breaking the unlock.

If you update to Apple’s new software using the normal iTunes process, you will lose your ultrasn0w unlock.  In fact you may lose it permanently, because for most people the baseband firmware cannot be reverted to a previous version (unlike the main application CPU firmware).

But don’t worry…our PwnageTool program lets you update your main firmware without touching your baseband firmware, so you can still have the best of both worlds.  But you must be diligent about saying “no” to your iTunes request this week to update your firmware.

As always, eliminate the middle-men and get the PwnageTool and all your iPhone accessories direct from the source.
