Hello everyone. I have a BB7290 which is giving me problems now. I cannot find anyone that can tell me what causing my problems and I thought maybe one of you may be able to help. my phone blanks out in the middle of a call and I have to take the battery out and put it back in for it to come back on. Sometimes I will get a device error message 411 Reset but I have not been able to get any decent info on this. If anyone can help I would appreciate it. The Cingular people just tell me I need a new phone and won't even assist me.
