I installed the latest version of Google Wallet 1.1-R63-V12 released a a couple days ago. This was the version that has the updates to support the EVO 4G LTE. It still doesn't work on our One X. Same error as before where it says the device has not been certified for our carrier/device.
The previous version was available for us in the Play Store, though it didn't work. The new version is not available from the Play Store. So I had to hunt down from another forum the new .apk. I guess it was all for not since it doesn't work. I'm documenting this so that others don't waste their time.
By the way my AT&T One X is rooted. I cleared the data and then uninstalled the old version first before installing the new version.
