Is it possible? My sister just handed me her old ATT IPhone4 IOS 5.0.1 model A1332 baseband 04.11.08_ICE_2_13. I am trying to make it work with my T-Mobile regular (not micro) SIM card. Is it possible to jailbreak it so that I can use it with my t-mobile sim card? I do not have the old shsh blobs saved and the apple store updated her IPhone to 5.0.1 with letting her know. Thank you for your help.
