Google is giving away $10 instantly on a prepaid MasterCard. All you need is a Nexus S 4G with Google Wallet. Once Google Wallet is installed, click add a prepaid card and in a few minutes you'll see your free $10 prepaid card.
I had to unroot my phone, restore the factory boot loader and flash to a factory ROM all in order to get the latest ROM from Sprint (2.3.7) which contained Google Wallet. Once you have the latest ROM though, you can always root your phone again. Was it all worth it for $10? Maybe
