I have an iphone 4 iOS4.0.0. baseband 01.59.00. I bought it from someone when he was still on a 2 year contract with ATT. He sold it to me with a software unlock included and the phone has stayed at 4.0 and not upgraded since. Now I really need to upgrade it because most apps require something more recent than 4.0. I was thinking iOS6 but the jailbreak is not out yet.. SO...... the question:
Can I upgrade it now to 5.1.1 while preserving baseband so I can software unlock the phone?
I do have SHSH for 5.1.1
and i know for me to preserve baseband i need a custom ispw but for 5.1.1 i also need a custom ispw.. so what do I do?
