What exactly does having a 3 year contract mean? Can you change your data plan? Are you stuck with the same phone for 3 years? 9 months ago I got a blackberry on a 3 year contract with Rogers for $75 a month and lately I've been really hating it and have fallen in love with the iphone! so I would love to get an iphone but I'm not sure what to do. If I am really stuck with the blackberry I'd just change my plan if I can even do that?

I've been looking for everything the girl gave me when i bought it (papers explaining my plan, etc) but I can't find it so I will have to go into Rogers but I just want some info before I do.

specifically though what can/can't you do on a 3 year contract with rogers?
