I have the Build Nokia 920 and AT&T is still having trouble with this phone. The tethering is turned off and multimedia messages do not work. Internet is ok. AT&T told me they do not recognize the phone (yet maybe later?) so these features are off. I am not sure how others are doing with this phone. Phone is nice, however, and it should do well. I am seeing if I can do some low level socket apps now.
Ah crap. No pics in SMS? That's not ready.
-- I'll insist on a store demo
