[quote=SmellsFeeshy]So if I get either the Infuse 4G or Atrix on AT&T will those support LTE once AT&T rolls it out? Or are they only capable of HSPDA?[/quote]
LTE is an entirely different network. So, the short answer is no. What I’ve read is that, even LTE phones between VZW and AT&T are not compatible due to the different frequencies that the 2 LTE network operate at.
