We're pretty excited about Google Wallet, but the service is currently only available for Nexus S 4G phone owners, leaving most of you waiting for broader implementation. Well, how would you like to skip the line, getting to test it out on a Nexus S 4G of your very own? Google has supplied us with five phones to give away -- the company is even throwing in $1,000 (yes, one THOUSAND dollars) of prepaid credit to help fund those first few dozen taps. There's one catch: you'll need to use your Nexus S 4G with a Sprint plan, though the carrier is throwing in one month of demo service to get you started. Check out our in-depth preview for a detailed look at the service, and simply leave a comment after the break to be entered to win -- after checking that you meet the entry requirements, of course.
