I am on metro by t-mobile. I received an update that I was unaware of.This app showed up as did the lock icon in my status bar and on my home screen. I guess this app, an unlocked, from the manufacturer phone and t-mobile aren't buddies. Now I have no data service and have spent the last two and a half weeks in and out of metro and t-mobile stores, approximately 6 hours total time on the phone and STILL HAVE NO SOLUTION. But yeah.The t-mobile app.Whoo. @$*!&#. Hoo. Now stop asking for my review
