Thanks for the free lunch Google/Nexus 7!!

I tried using the N7 at a Best Buy but it didn't work. Best Buy apparently has a problem with their systems. The employees acknowledged it. I for one am shocked and chagrined that Best Buy would fail at something :p
 
Go to the Google Play Store, go to your apps, swipe left to bring up all apps and scroll down to Google Wallet, it is not in alphabetical order, then you will see you can update.

I didn't have the icon to update, only install, so I re installed from the playstore and got the newer version
