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.
