Apple‘s iPhone can be had without a contract. Just walk into an Apple Store, fork over $599 and you’ll be set with an 8GB iPhone. Too easy? Then walk into an AT&T store. You’ll need to be an existing AT&T customer. You’re also limited to just one.
What does this mean? Are you on T-Mobile or travel abroad frequently and want to use an iPhone? You still have to unlock it since it is technically locked to AT&T’s service. I’m guessing Apple will give you that unlock code. After unlocking the iPhone you can stick your SIM card of choice and use the iPhone anywhere there’s a GSM network. Finally.
