Last night around 2am I was messing around downloading apps and stuff and playing online. Then all of a sudden I got an error code and lost all internet connection. Tried rebooting, changing data connections but nothing. I was only able to use the phone to make calls, no texts or emails or internet. When I woke up this morning, everything was working fine but now whenever I type for a text or browser, my phone makes the most annoying sounds. I have it set for audible touch tones to be off and yet it still makes sounds. Nobody can figure this out. Help!!
