iPhone Dev-Team Warns Against Updating to iOS 4.1

The iPhone Dev-Team has issued a warning to remind users not to update to the new iOS 4.1 firmware that is expected today.

Today you’ll likely start seeing iTunes innocently offer you a new version of iOS…version 4.1. Don’t accept it…it’s a trap!

This time of year there are lots of new iPhone owners, and not everybody knows that accepting new iOS updates is the surest way to lose your jailbreak and/or unlock. While those of you who have Cydia or TinyUmbrella backups of your FW hashes will always be able to get back to 4.0.1 if you make this mistake, this doesn’t hold for unlockers. There’s currently no known way to revert your baseband — if you update your baseband you’ll lose the ultrasn0w unlock, possible forever.
