Unlimited Calls + Data on Blackberry $60 - $80 Month

If you use a Blackberry, listen up! Instead of paying a fortune to your regular cell company (typically $30 extra on top of your minutes/text plan's cost), you can now get unlimited service (calls, text, web, email, data) for $60 to $80 a month. Of the three offerings, Boost Mobile's (owned by Sprint) $60 deal seems the best. It uses the Sprint network (previous only Nextel's net). The catch: you apparently cannot bring your own phone, you have to buy their Blackberry Curve 8330 for $249. Keep in mind, the monthly savings will pay off the phone in less than a year.
