The Blackberry Curve 8310 is similar to the 8320 except it loses Wifi and gains GPS capability. The 8310 retains all of the functionality you would expect from a Blackberry phone and adds a camera, expandable memory, media player, bluetooth, voice dialing, maps and trackball navigation.
Buying a replacement phone will not affect your existing service contract, but are generally more expensive, since they are not being discounted by your carrier.
