Should I get a blackberry (9310) on boost mobile?

That sounds like a deal.

I'd recommend that you check the retail price of the phone without a new account or service and see how much you're saving. Also, can you afford the monthly payments? Often, when a carrier states "unlimited" web or whatever, it'd do you well to read the fine print. And be sure that, if you have to sign a contract, that it's a phone you'd want to be stuck with for the next two years. Don't go with a phone just because it has all the latest features and such, as new phones are coming out all the time.

RIM makes good Blackberry phones. Just do your research. Ask around. Get a phone that suits YOUR needs. Read phone reviews online. Keep your options open.

I'd recommend a GSM (SIM) carrier over CDMA, as you have greater flexibility.
