    Hi, i have a iPhone 3gs 4.1 new bootrom, unlocked with the ipad BB 06.15.00. Has there been way to upgrade to the newest firmware while preserving this unlockable baseband? I heard you wouldnt be able to even restore it cause of this baseband?

    If you have a Mac, I can recommend using PwnageTool. If not, checkout TinyUmbrella
