As you may recall, T-Mobile began offering the iPhone 5 in April, and unlike other carriers, your phone comes without a contract. You pay $99 down and $20 per month for two years. And according to AppleInsider (via TmoNews), this weekend T-Mobile is offering a special deal for Mother's Day: trade in your old iPhone 4 or 4S, and T-Mobile will give you the iPhone 5 for $0 down. In order to an acceptable trade-in, your old phone must be in working order: name, be able to be turned out, not have a cracked screen, and not have any physical or water damage.
