Around where i live i get perfect signal but at work i get less signal than what i did with my 3gs. Sucks cuz the main reason i switched to att was because i didnt get any tmobile signal where i worked. Switched to new iphone, back to no signal at work. And when 4.1 releases, its said to show less bars? What if you have no bars to show in the first place? And what about at home with my "perfect" signal? Will that be shot down too when 4.1 hits? Despite my Problems/complaining, i love my iphone 4 and if there was a recall (doubt it) i probably wouldnt give it up.
