I replaced the screen on my 3gs 2 days ago, while I had it tore down I decided to go ahead and paint the shell. I put it all back together last night and now I have No service. I reset the network settings and I get 1 bar for all of a minute before I am back to No service. I also have no sound but other than that everything else including my wifi works fine. I checked the two metal tips and both are touching the case and all of my connections are there. The phone is still under warrenty but since I painted the shell I dont think they will do anything about it. Any ideas or is it a lost cause?
