I am new to Iphone , I've got an Iphone with turbosim card, and it's working perfectly (I guess lol), Itunes's asking me if I want to update to 1.1.3, I am in canada. can I update it or it'll be locked again?
TurboSIM won't work anymore once you upgrade to 1.1.3 with iTunes. You'll then have to use the ZiPhone (or some other) method to re-unlock and jailbreak your iPhone.
