How to Jailbreak and Unlock iPhone 3GS on a Mac
I apologize in advance for asking for help for something seemingly minor but...
My sister gave me her old iPhone 3GS, the screen is broken...I thought I'd try to jailbreak it then unlock it so I can use my T-Mobile sim with the phone but I can't seem to figure out how to do this. Any help would be awesome.
I did restore it to iPhone OS 4.3.1 which may or may not have been a mistake but I wanted to update it first.
It also has Baseband 05.16.02-6.4_M3S2.
I've been trying all day and can't seem to figure it out! I can't seem to restore an older operating system either, I figured that might be the easiest thing because untethered jailbreak of 4.3.1 does not seem to exist yet, but untethered is not important.
Would I put the new sim card in before I do all the jailbreaking?
Thanks in advance for any help you can offer.
