Hi Scott,

I'm currently using the Tmobile Wing which is also made by HTC and I'm loving it. It is basically the same as the 8525 (I think) from AT&T and it's lacking the tilting feature.
I went with Tmobile since AT&T coverage is horrible down here in San Diego. It runs Windows mobile 6 and does run Skype as well and beats having to carry PDA + phone at the same time. I know you'd probably go for AT&T because of the 3G functions but I thought I'd mention that I'm very impressed by any phones from HTC.
