Hi, my iphone's signal varies between 4 or 5 bars to no service. This annoyingly happens both at home and work. Today I brought a SE k850 in to work and compared the signal. The k800 stayed a fairly constant 4 or 5 bars and the iphone varied between no service and 5 bars. When I find time i am going to take phone back to apple store, but as the signal in centre of town is always strong I have taken some pictures of both phones side by side, so I can show it doesn't always work. Anyone else have this issue? I know there is a discussion on this topic on apple's support site but I haven't seen anything here.
