T-Mobile has recently announced a new promotion in which many phones that they offer from Samsung will be available for free or free with a rebate. This promotion will start on September 3, and will probably end a month later, although an official ending date was not announced.
With a new contract or phone upgrade, you can get the Samsung T229, Samsung T429 or the Samsung T339 for free. The Samsung T639, Samsung Blast and the Samsung Katalyst are all free, however they require a mail-in-rebate $50 rebate. The last phone, the Samsung T819, is also free and that comes after a $100 mail-in-rebate. This might be a good way to attract some new customers for T-Mobile as they have been known for their promotions.
