I just unlocked my OTB 1.1.2 iPhone using the NextSim4 that I bought on eBay. The good news is that it is working perfectly on T-Mobile! However, it looks like all the contacts/directory from my old phone that are stored on my T-Mobile SIM do not show up on the iPhone. Is this normal? Is there any way I can retrieve those or do I have to put the SIM back in my old phone and copy down the contacts by hand? Also, my friend used his PC to do the unlocking so the phone is attached to his iTunes. How do I change it so that it syncs with the iTunes on my Mac? I don't want to undo anything he did with the whole unlocking and jailbreaking, etc. Also, is it possible for my to upgrade to 1.1.3 now? Again, I don't want to do anything that will brick my phone. Thanks in advance!
