I'm going to keep this as brief as I can. I am now on my 4th, yes FOURTH Dash from T-Mobile. While the phone carries a lot of very useful features and seemingly easy to use interfaces it is incredible poor on performance.So far I have experiences freeing, random reseting, lock outs, full failure, inability to dial out and other random problems. I can't tell you if it's the phone or Windows Mobile 6, but regardless of which it is it makes the use of the phone frustrating and almost downright worthless.Because of all the problems I'm switching over to the Blackberry Curve. Maybe I will have better luck as my friend is having better luck with his Blackberry Pearl (after having 4 Dash's himself). Even a T-Mobile store rep has told us of the numerous problems people have had with the Dash and it's sister phone the Wing.
