which is betteriphone 4 or bb

Better at what ?
 
I have both- if you are not tech savvy, then go i4. easier to learn, more to do. I don't much care for BB products anymore.
 
RIM is on the way down you'd be better off with either Android or Apple.

I have a 9800 BB Torch Virgin Mobile super tab no contract! Pay off phone if I want to go a other provider! 10 percent of My bill each month goes towards payment of my phone. Bell network. No better deal around.
