I just purchased an iphone 3g but unfortunately it came out of the box FW 2.2.1 with baseband 02.30.03. I know yellowsn0w doesn't work with this baseband but has anyone tried 2.2.1 turbo sim? I read that its sorta glitchy, is that true? I wanted to get this for my girlfriend for her bday and unlock it for Tmobile. Anyone have any experience with the turbo sim for 2.2.1 or should I wait till the iPhone dev team release Yellowsn0w that will work for 2.2.1?
