Hello macrumors, My friend has an iPhone 4 4.3.3 Tethered (Gevey Simed) for T-Mobile. To simply untether it can I just go to jailbreakme.com and rejailbreak it? Without messing anything up? Thanks guys and gals.
You cannot use jailbreakme to JB if you use a Gevey sim Have your friend run Redsn0w on phone, uncheck install Cydia It should untether it. Make sure they have 4.3.3 hashes saved, if not, use iFaith to save them before doing any alternations to the phone.
