I am a Sprint customer andI upgraded my cell phone to a Blackberry Curve 8330.I was concerned because I am kind of technically challenged.To my surprise I have learned to operate the phone quite easily,and if I get stuck on something the manual is simple enough for me to understand.I was interested in this phone because of the quality pictures it takes,full keyboard,and its durability.I have a cat that climbs on the nightstand and pushes my phone on to the floor so you can imagine my concern of being damaged or broken.I spoke to a few people who have this phone and they all highly reccommended...
