If you must go to a windows mobile device (anytime in the future), I would suggest the att 8125 or tilt version of that (I think the blackjack and tilt cost the same for monthly charges). I realize it costs more to buy then a blackjack but my father owns one and feels it is superior to blackberry and the iphone. It has little flaws and the only real problem is it is big. Good to here blackberry is the same price.
