yes. i'm still not sure if at&t sucks or if its the iphone sucking but there are a lot of places that i've been to lately where i've had 0 or 1 bar and the call just drops out on me. ..and i should add that it's urban places that other at&t phones might have 3-5 bars. (admittedly sometimes they are big box grocery stores but i never had a problem with verizon and my old phone)
