Will I notice a difference in voice reception, coverage and reliability with an AT&T iPhone 5 compared to my current AT&T 3GS? I'm facing a choice perhaps others are too: I have been using AT&T (unhappily) for a few years with my 3GS. I absolutely detest the voice service - crappy quality, dropped calls, long connection times, etc etc. However, I do like to multi-task (esp talking while driving and have maps work for directions!), and I'm grandfathered in to the unlimited data plan. If voice service will be the same as it is for me now, however, I'm bailing to Verizon (no land line and sick of AT&T voice). Would love to hear your experiences - will the 5 improve my service? I live in Berkeley, so Bay Area performance is important. Thanks!
