Rogers also has the 1gig plan for 65 bucks that is flexable, meaning go over the 65 dollar 1gig and you get billed 75 for the 1.5 gig....alot of people believe this is only for network cards or laptops, but it can be used for devices that tether as well, so call them up and tell them you tether with your 8310....read the fine print it says it is available for blackberry and non blackberry as well
