Dev Team Warns Jailbreakers & Unlockers to Avoid Upgrading to Upcoming iPhone OS 3.1

Jailbreak iPhone 3GS using redsn0w on Mac

Apple is planning a special media event "It’s only rock and roll, but we like it" tomorrow where they’re expected to announce the release date of iPhone OS 3.1.

iPhone Dev Team has just published a post on their blog to warn users who have jailbroken and/or unlocked their iPhone that they should avoid updating their iPhone via iTunes if Apple releases iPhone OS 3.1.

iPhone Dev Team have given the following warning to users who have jailbroken and/or unlocked their iPhone:

This week Apple will be all over the news with their announcements at Wednesday’s “Let’s Rock” event.   But with so many new owners of the iPhone 3GS, and with so many new owners of the iPhone 3G (perhaps sold to them buy these new 3GS owners)…now is a good time to send out this general advisory.

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 let’s 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.

We’ll keep you posted if there are any further updates so stay tuned at iPhone Hacks.
