Yeah, we know how happy you felt when you received that email from AT&T but you may want to stop and think first before doing a full restore that was suggested by AT&T.
UPDATE: If your request was rejected, you can still unlock your AT&T iPhone permanently. See here.
You should have known by now that if you do a full restore, you will:
- Update the baseband
- Lose your untethered jailbreak (if it’s jailbroken)
While losing your untethered jailbreak is not really the end of the world but losing your valuable baseband is, at least for many people!
Why? Many people who have received the unlock confirmation email from AT&T got too excited and did a full restore as suggested by AT&T. However, for some reason the unlock didn’t happen as expected; like what happened to one our Facebook followers:
There are two “safe” ways of unlocking your iPhone:
- Use the latest redsn0w (no restore required) – simply launch it, click on Jailbreak, follow on screen instructions, uncheck ‘Install Cydia’, check ‘Deactivate.’
- Build a custom firmware with sn0wbreeze (restore required) – launch program, follow on screen instructions and choose baseband preservation mode – this allows you to restore your iPhone to “stock” custom firmware while preserving its baseband.
For both methods above, once you have completed the steps, eject the iPhone SIM tray, connect to iTunes and you will get the following message:
In case you don’t see the screenshot above, that tells you the unlock (and activation) was not successful. Check with AT&T again on the status of the unlock.
If you’re still waiting for that unlock confirmation, be sure to take precautions before you proceed! Losing your unlockable baseband is the last thing you would want to happen to your iPhone!
