CBS has Blackberry Enterprise Service licenses available for Blackberries. All you have to do is bring your device to ITG, the IT support group on the second floor of Uris Hall. The current charge is $140 for two years ($100 for a one-time license fee and $20/year). I don't know whether it goes on your tuition bill or if you can pay by credit card. And I think it's pretty much instantaneous - they'll set you up right there once you've paid and you should be good to go. I think at one point there was a way to do it online, but I don't know if it's still there, so your best bet is to just stop by ITG after you've activated your email account (during computer setup in August). Then you should be good.

If you do not want to pay for Blackberry Enterprise Service but still want to receive your emails, see the FAQs on the Email on Mobile Devices page.
