have had 8125 and tilt w/ at&t, besides the (obvious) microsoft glitches, they are pretty badass phones (internet explorer gets streaming vids, win media player, fully customizible everything from rings to alerts to everything). HTC is all about excellence. I have several friends with the iphone, looks cool and love the motion shit it can do, and overall is ok; but what?! no pic messaging? pffft. Stick with HTC for the win! Fuze will mosdef be my next phone in march. This phone called fuze for at&t. only downfall is the fact that touchscreen phones cannot be warranteed, but so what. g1= not so fly.
Just my opinion, get whatever you want/can afford.
