Hi guys. I am really frustrated the way my Nokia 6085 loses signal and even drop my calls in between. Now I really want to upgrade my phone to help with my crappy AT&T service which is really weak at my house. One of my neighbors suggested me LG CU-500, as it was the one he was also using in the same area. But now I really want to be careful while I purchase my new phone. So please come up with some good options which can help me to pull myself out of this situation.
