I have a charge and I downloaded an app off the android market called Internet OnOff Free to turn the 3g on and off so i could save battery when i wasnt using the internet and now my 3g doesn't work. If I go wifi I can use it. The 3g is just not working. I took the phone to a Verizon store and they said that they might have to wipe the phone or possibly give me a new one. They switched out the sim card but I don't think that worked. Has anyone else had this problem? Any help would be greatly appreciated.
