MuscleNerd: iPhone 4 Unlockers Do Not Update To Stock IPSW

MuscleNerd just tweeted a reminder to not update to a stock firmware because that will update the baseband, and you will loose your unlocking ability.

We just told you that greenpois0n, the first jailbreaking tool to use the SHAtter exploit is scheduled to be released Sunday 10/10/10, so that’s great news for everybody who has a iOS 4.1 OTB iPhone. But for the rest of you, MuscleNerd just tweeted a reminder to not update to a stock firmware because that will update the baseband, and you will loose your unlocking ability.

It seems that a new version of PwnageTool is in the making – which will let you create custom IPSWs , and won’t update the baseband – but, there’s also a workaround ( for iPhone 4 ONLY ) , through TinyUmbrella.

Stick around, we will post a tutorial on how to do it in a second… ( tutorial here )
