Google Wallet has finally arrived on Sprint's Nexus S 4G in the form of an OTA update rolling out now. Samsung says that software version GWK74, which contains some security fixes along with Wallet, is pushing to users sporting the latest software build (GRJ90). If you're a few updates behind, you'll have to try to pull this one manually, as you probaby won't receive a notification. Sit tight if you're not seeing it yet, and sing out below when it hits.
Google's also putting its best foot forward on this limited launch. Check out the video after the break.
