I picked up a Motorola MPX200 for a good price and it was unlocked. I
currently use Cingular as I get a great discount thru my work. The Phone
was originally used on ATT but was unlocked and when I switched it over to
my service it was ok but I started noticing that I would drop a call just by
moving and friend started saying they had tried to call me and would get
messages saying that there is no service at this number. Any help would be
greatly appreciated
