I’ve been using my Blackberry Curve 8310 for 6 months now and I truly believe I could not live without it.  In my opinion here are the best features of the Blackberry Curve.   My Blackberry 8310 seems to be durable.  I’ve dropped it (more than once) on concrete and it seems to be unphased.  Secondly, I love the camera on the Blackberry 8310.  The pictures come out looking great thanks to 5X digital zoom.  And thirdly, the Blackberry Curve is easy to use.  I had mine figured out in a matter of days, and I use every feature on it except for GPS.  Just haven’t activated the GPS yet.  Here is one thing I think could be improved with the Blackberry Curve:  the buttons are very,very small.  I do fine with them, but it’s obvious that someone with bigger hands might not do so well.
