That is an AT&T issue. I ran into that because I was in the US when the PlayBook was released. Even though I'm a Rogers customer I was in AT&T land so I couldn't download the Bridge software from AppWorld. Back in Rogers coverage the Bridge works exactly the way you would expect, and if you have a 500MB or greater plan they include tethering and support Wi-Fi hotspotting on OS 7.1 handhelds.
So, if you're going to stick with AT&T iPad/iPhone/Android seem to be the best solution for your needs.
My other Blackberry is a PlayBook.
