I'm sure this has been answered somewhere on the millions of posts here but I honestly don't have time to go through them.
I just got an iphone 4s here in Hong Kong through my Landlord who I think got it through the carrier 3.
How can I do a few things...
Make sure it can be used in USA... I heard the SIMS card is different and it can't be used there.. is this true?
Do I need to jailbreak and unlock it as well and where can I do this? Thanks!
