Heads up guys.. There is a new update for Google Wallet on the market tonight. I updated mine and when I went to run the app, I got a message saying my Google Wallet hasnt been certified on my device/carrier and then the app quits. I am bone stock running 4.0.2.. not rooted or anything.
I uninstalled it and re-installed the leaked version and it looks like everything's back to normal.. I dont know if it's just me and my phone, but just giving a heads up in case someone else has this problem.
EDIT: Looks like it might have been something unique to me since many others are updating with no problem.
