I'd like to know how just how well the AWS iPhone 5 performs on T-Mobile. When I had T-Mobile, their AWS devices would often switch to EDGE in good covered areas. I found the constant switching to kill my battery. Then at home I'd have full 5 bars of EDGE only. What I'd really like to know is, what happens in areas where T-Mobile has already refarmed to 1900 PCS 3G? Many have reported the iPhone prefers AWS 3G, resulting in weaker signals. With T-Mobile using 1900/AWS frequencies, their in-building coverage will be inferior to AT&T. So can those using the iPhone 5 with AWS support comment on the network experience? Preferably those in good to excellent coverage areas.
