T-Mobile iPhone 5

T-Mobile is offering a generous deal to lure iPhone users over to its service once it finally begins to carry the iPhone 5 this Friday.

A new trade-in plan will allow customers to pick up the iPhone 5 with a zero down payment and up to $120 credit, which can be used for monthly payments towards T-Mobile's "uncarrier plan" or old phone bills. All owners have to do is bring in an activated iPhone 4 or iPhone 4S.

"Our message to iPhone 4S and iPhone 4 customers is simple: bring in your device and trade up to iPhone 5 on T-Mobile," said Mike Sievert, chief marketing officer for T-Mobile. "We're making it incredibly attractive to buy an iPhone 5 by pairing an un-beatable upfront price and trade-in offer with Simple Choice, the most hassle-free and affordable rate plan in wireless."

The trade-in offer is valid until June 16th.
