Downloaded 4.1.2 on my TL and it is pretty cool. UI is much snappier and smooth, and the Extended Battery mode option is fantastic - saw that option on some other Sony devices so I'm very happy they updated the TL with it too.
Confusing issue about Google Wallet... has anyone tried using it? Despite being on AT&T (which apparently doesn't "support" Wallet) the Google Play store let me download the app - which initially made me pretty excited - only to be slammed with a pop up as soon as the app starts claiming my device and/or service provider is not supported. Previously the app did not show up in Google Play (most apps that are not "compatible" with the device you are using will not show up), but when I noticed a few extra features in the settings -> more under NFC for Wallet, I figured then Google Wallet was compatible lol.
Works with CM10 on the T, I haven't had a chance to test it with stock Sony firmware yet.
