I did a factory reset on my son's razr maxx HD because he simply installed too many apps. I entered my gmail account info and password during the setup wizard and I didn't see any special. Next I launched Google Play Store to update his apps and to my surprise ... a window opened that read ... "Welcome to Google Wallet: Cancel or Continue". I entered my gmail info and completed the setup. App works great for purchases and browsing the receipts of my previous purchases. Now I am waiting for Verizon to allow it to work on MY phone ... Samsung Note 2, but for all you Razr users ... ENJOY!
