I recently upgraded from a 8100 Pearl to the 8310 Curve and can say its the best decision I've made in months. This phone is simply fantastic. It's not as pretty as the over-hyped Iphone but functionality-wise, there isn't much out there that can compete with Blackberry. Getting used to the new phone will take a few days but once you get the hang of it, you will be very pleased.
