Go to Manage Connections > Mobile Network Options. Is Network Technology set to GSM/UMTS? If it isn't, it needs to be.
To change My Number, dial ##000000
Change the Mobile Directory Number to whatever number you want it to be, press the BB/menu button, select Save, let the phone reset.
I could be wrong but you would have to push the service books for rogers and have a BB data plan with them.I'm not sure but would the PIN need to be released to Rogers BIS to work with their service?I know there are people here that use the Storm with Rogers so hopefully they will chime in.
For item 1 does the phone say edge or EDGE?
You won't have a browser till it says EDGE. This may depend on what Os you're running. Some of the later os have trouble with EDGE. Do a search on that. If you have EDGE, go into the setup folder and click email setup. Setup an account for your BlackBerry. It will then send the service books.
