The geek chic Motorola V60i is available for free on Amazon.com after a $200 rebate (actually one for $50 and one for $150). Unlike a lot of current rebates, you don't have to go with T-Mobile--it's an ATT rebate.
The best feature of this phone is the outside screen that displays the time normally and caller ID info when a call comes in.
The phone is lax on power user features, but it's small and stylish (for a flip phone). The $150 rebate ends March 25th so if you are looking to get this phone you better move quick!
