Fancy a BlackBerry Curve that earns you $50? At the moment, Wal-Mart is running an online deal that means the normally $149.99 phone will cost you just $49.99, and after rebates you'll actually be $50 in profit. The T-Mobile Wing and BlackBerry Pearl (normally $299.99 and $99) are also going for free, and will get you the same $50 rebate. There's a long list of other phones on similar deals from the MOTORIZR to the Samsung Blast: check out the Wal-Mart link. [Wal-Mart-Thanks Shiron]
