No signal all of a sudden? Hey all, I've my Q9c with Sprint for a little over a week now. I plugged it in last night to charge and when I woke up it was off and I couldn't get it to turn on. I took the battery out, put it back in. Nothing. Did it again a few times and finally it turned on. Now, in an area where I previously had decent coverage, I switch between low service and roaming constantly and I can't make/receive calls, access the internet, or send/receive text messages. I've been in the que for "advanced technical support" for almost 30 minutes now (calling the business line even). Does anyone know what the culprit could be?
