Hey, all you Sprint Premiere customers out there: Your favorite carrier's looking to give away 10 -- count 'em, 10! -- Evo 4G phones, four tips to either Maui, Chicago, Las Vegas or Houston (coincidentally, four cities with 4G), and $4,000 in cash. And it's all in the name of launching the biggest Android phone yet, as well as the first one sporting WiMax. You have to already be a premiere customer, so common folk need not apply, apparently. Be sure to check out all the official rules and what-not. [Sprint] Thanks, everyone, for sending this in.
