Apple is expected to announce the release date of its upcoming iPhone firmware update: iPhone OS 3.1 on the special media event “It’s only rock and roll, but we like it”.
The legendary iPhone Dev Team has once again warned all the users having Jailbroken iPhone or Unlocked iPhone to avoid updating to iPhone OS 3.1 via iTunes. If you do so, you’ll lose your UltraSn0w unlock, consequences may also be a permanent lock.
Dev-Team issued the following warning to jailbreak and unlocked community:
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.
