As in my other post I take care of my devices, plus this one is no more than 1 week old. I'd just rather not deal with the idiots at the store. I did however swap out the data cable to test that (it wasn't working with my 8310 either, 2 birds 1 stone). It will stay connected until the "there are updates for your software" thingy pops up, I should probably click no, but my clicking finger is sometimes faster than my brain. Then it restarts, & no longer will read the device at all, not even the charging icon will pop up. I tried charging it too & for some reason no go. Anyone know why its doing this???? HELP!! Its frustrating, I just want to switch devices.
