My company got us all sprint curves but then a few months later decided sprint sucks and got us all new curves (8310) from cell 1. so I hear they will offer them to us for $50.
Q: is it worth it to buy it
Q: what uses are there for it with no service.
The 8330 is a more capable device than the 8310, so you could turn around and sell it quite easily, there are people that would help you double your money or better for a nice used Curve. Average for one in nice shape is around $150 or more. Not a waste, for a clean device.
