IPhone or Blackjack 2????

i would go with the iphone but then again i have one and sometimes the touch screen doesnt respond and freezes up alot and the black jack 2 is also pretty cool but it can have some problems (my friend has the black jack 2)like it can not get the A-GPS to work with Google or Live. and it doesnt have a scroll on but it has a rottating d-pad witch makes it a little harder to get to things so to be honest i would go with the iphone its a good phone it has so many features and you can also can hack into it and put more things on it
