Please help, Browser not working

Ok I recently had the G-1 with tmobile but I just purchased the BlackBerry Torch from AT&T and unlocked it with Tmobile. My internet browser will not work though Ive gone through all the step from customer service and all but its not working. People on here are saying it works and are giving directions but only for the ones that had a blackberry before the Torch. But I had a G-1 so the directions they're giving aren't going to work for me. Help anyone

Do you have a Blackberry BIS data plan? If you do not then you will need this for your Blackberry to work properly.

I swear one of these days I'm just going to STOP clicking links with non-specific subject lines. If I had known what this was about by reading relative content in the subject line I could have saved myself the time to look because I can't help you anyway.
