meh, hd700 or not, i'm not going to spend whatever they're going to charge for it to own one. after i get my dac-ah, i'm going to call it quits on headphone stuff and focus my attention on speakers and home theater stuff.
never had a problem with AT&T as well. the only thing that really sucks about them is their fucking customer service, which does so shitty every year, yet they make absolutely no strides to make it any better. oh well...at least my iPhone keeps me happy.
