My nexus one recently doesnt show the 3g icon next to the bars. I don't believe it lost the 3g signal, as I can see 3 bars in there and when I force 2G it goes to 4bars with the 'E' symbol. It just doesnt seem to get 3g data, i believe. I can call and text, but when I try to access the net it says site not found. Could somebody explain why this is? I have T-Mobile in midtown atlanta.
