Sprint’s first HTC Evo 4G giveaway included paid vacations, but its was open only to Premiere customers. This new Facebook contest makes any American adult eligible to win one of ten Evo 4G super-smartphones.

To enter, simply fill out the short form on Facebook and wish upon a flying star. Sprint’s 4G service fees are not part of the prize, so winners will have to pay $69 (minimum) per month to keep the phone up and running, and of course, WiMAX coverage is pretty narrow at the moment.
