When i first got the phone 2 weeks ago, it worked... my pc recognized the connection and I could access the folders on my phone, just like windows. Now when I connect it, all it does is charge my phone. I go into Settings/Wireless & Networks/USB utilities/Connect- when I hit the tab, it tells me that the USB is Connected, remove cable, then I do and then it tells me no Cable, to connect attach cable. This is a vicious circle. Please help.
