Unlocked iPhone

We believe that Apple will be releasing the iPhone 3.1 update at or following tomorrow’s “It’s only rock and roll, but we like it” special music event, the members of the Dev-Team has posted a reminder for Jailbroken & unlocked iPhones:

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).

A custom IPSW is needed to update to this firmware so that the baseband won’t be upgraded allowing users to continue using their unlocked iPhones without issue.

So, jailbreakers and unlockers, DO NOT UPDATE USING iTunes! You’ve been warned.
