I actaully switched to the Tbolt for Verizon. I had the Atrix before this on ATT and absolutely loved the phone. But ATT being the scumbags that they are, really have no such thing as 4G and on top of that, they make their 4G experience subpar by capping upload speeds on the Atrix. Overall a shitty experience. I took the phone back the week the Tbolt came out and never looked back. I love the phone just as much but the service is without any equal. F Att and Go VZW!
