MuscleNerd To Release Updated 06.15.00 Baseband Downgrading Solution For New Bootrom iPhone 3GS Today

A few weeks ago MuscleNerd released a baseband downgrading solution for any iPhone 3G or iPhone 3GS running the special iPad 06.15.00 baseband. This solution came in the form of a new feature in RedSn0w, and it easily allowed those who were previously trapped on 06.15.00 to downgrade back to a fully functional iPhone baseband. Unfortunately newer bootrom iPhone 3GS owners trying to use this solution had no luck, and often encountered “no service” errors.
Near the end of June we told you that MuscleNerd would be working on an updated version of the 06.15.00 baseband downgrading solution to fix problems being experienced by newer bootrom iPhone 3GS’. The only thing that was holding MuscleNerd back from releasing this update was having a physical device in hand to test it on. Luckily MuscleNerd managed to get one sent to him, and after just a day of debugging MuscleNerd has tweeted he has revised the payload and he will release the improved downgrade later today.
