Can I unlock iphone 5 even though I no longer have an account with att?

I have a phone for att, but I no longer have an account with them and the phone is just sitting there so I want to activiate it on tmobile, how do I go about getting it unlocked?

Yes you can but its gonna cost you, I've unlocked a few phones this way simply get on YouTube and in your case search unlocking an iphone5 you'll find a video with step by step instructions but this is only one half here's where it gets expensive there are several sites online that sell unlock codes you'll need to buy one and its very expensive android codes are a little cheaper but being a 5th Gen iPhone you're looking at up to $75 for a code keep in mind you'll need a debit or credit card for this best of luck

  • Should I update my iTunes even though i still have iOS7? I have an iPhone 4 so I can't get iOS8. But lately iTunes has been sending me messages asking if I want to update, but they're all meant for iOS8. I don't want to download it and have it mess up my phone somehow. But at the same time there are security updates that are usually important. So what should I do?
