I think you should get the iPhone out of both phones you said. The iPhone has a much bigger and nicer touch screen with an easier to use touch interface (multitouch). It has many more applications and better hardware specifications.
I KNEW THIS WOULD HAPPEN.. pretty much knew it would be you :@
I'm not a fan of the iPhone, but Blackberries are just terrible.
I am most inclined to agree with you. For a normal phone a Black Berry is just awesome. For use abit beyond that there is a broad range of Android or iOS devices which are better for your needs.
