I don't know what I think of the reception yet...it isn't as bad as I thought it was going to be...I lose reception in my house a bit and unfortunately at Bolling AFB where I work(indoors) mostly. But, I have been able to make calls in a Target in Burke where I couldn't with VZW....overall it has been much better than I expected, but I have noticed that even with 3 or 4 bars showing it can take a while to decide to put through a call. It is definitely not as good as VZW in my situation, but I think it is good enough for me, cause I love web browsing, the sms interface, visual voicemail so much that I am willing to give up some reception.....it has been pretty good outdoors in Springfield, Burke, Arlington and better than expected in some buildings.
I was at Bolling for a while. There is actually a nextel repeater there. It was by the BITS office. I dunno where they may have put a permenant tower at. So having any AT&T reception is freaking great. I seem to remember Blanchard barracks being the best test for a cell. Reception there was always a crapshot.
