Hi, I own a Samsung D500 Unlocked Phone I bought on eBay. I recently moved to a different State in America but I have the same Cingular Service. My Problem is I'm getting no service whenever I enter a building, but when I go outside I get a couple bars. (roughly two maybe three depending on where I stand on campus) When I go downtown, I get a lot of service. The funny thing is that the crappy Nokia phone that came with the plan gets full service EVEN IF I"M in the ROOM. So I'm saying to myself, wtf did I just spend 150$ on this D500!!! I'm not sure if you are experiencing the same situation here and if you have a solution, it would be GREAT!!! Thanx...
