I have a blackberry with bell canada and I still have 2 and a half years to

go on my contract but i want out? how much will it cost me to get out of my contract when I still have 2 and half years to go on it and its a 3 year black berry contract.

Wait a month or two if you can. In Feb you are supposed to be able to move cell phone numbers between cell phone companies in Canada (ie a Bell number to Telus). When this happened in the US plans went down, and competitors actually swallowed the cancellation penalties in the form of credits to get you to switch. If you can wait, and want to change, you should see what happens.
