Hey, I am considering getting my first Blackberry, the Tour to be exact. But, I was wondering that since there is no WiFi onhe Tour, what exactly am I missing? (please note, I am not that phone savy.) I am looking for something that allows me to read and store PDF files. My coworkers have the 8900 and the bold. They listen to radio stations from allover the country, if they didn't have WiFi would they still have it? or would it work as fast?

Thanks!!
