I just went into verizon to figure out why i can't use my phone...when I try to turn the phone on it shuts right back off and says invalid battery...let me tell you it's not the battery...it's the stupid phone!!! I've had sooooo so many problems with this phone and I am NOT a happy customer because they will not let me upgrade. The phone is a piece...they keep sending me a new one of the same phone. This will be my third droid phone. Needless to say if i still have problems which im sure I will I will be switching providers! I will now be 3 to 4 days without a phone.....Very unhappy customer!!!!
