Many users, upon booting up their brand new EVO LTEs over the past few weeks, were confused to find that Google Wallet would stick in the "adding prepaid card" dialogue, often returning an error message which encouraged users to try again later. It soon became apparent that this issue was limited to the EVO LTE, as it was discovered that modifying the device's build.prop to identify as a Galaxy Nexus returned the app to full functionality.

CyanogenMod 9 may still be a ways out, lending some credence to the claim that upgrading from Gingerbread to ICS is a very long endeavor. However, if you're willing to live your life on the bleeding edge, and you own an international Galaxy S III variant, then the time is right for you: CM9 nightlies are now available for your device.
This is, of course, still an early build, so expect some bugs along the way.
