I will keep my TP2 thanks.
It is the best phone I have ever owned.
Heck, I am in Bahrain right now, with unlimited HSDPA data, and I am still on the Sprint network. I have no needs that this phone does not provide.
That being said, I would not mind a faster processor, but I am not sure I want a capacitive screen. Unless you write all the graphics around large icons, having a stylus is VERY nice for web surfing. Anyways, I am happy with my TP2, VERY happy.
P.S. This won't stop me from getting a unlocked GSM HD2 while I am over here, just to check it out at some point... You should see all the Nokia phones over here! CRAZY!
