I am not sure when this changed but its news to me so I thought I would see how many others have noticed it. Originally when the PlayBook launched you were able to browse the web through the bridge browser on AT&T which caused AT&T to push RIM to block bridge app downloads for AT&T customers. Then RIM gave AT&T the option to block browsing over Bridge on AT&T and knowing the wonderful people at AT&T they immediately went about blocking it.
Now with PlayBook OS 2.0 I can suddenly browse over the BlackBerry Bridge Browser again on AT&T through my BlackBerry Bold 9900. Both the native PlayBook Browser and the Bridge Browser are working over AT&T’s Bridge connection and they are super zippy. The only reason I can think this might be intentional on AT&T’s part is because I recently had to switch from their grandfathered unlimited plan to their $30/month for 3GB plan.
If you are an AT&T BlackBerry user and PlayBook owner please let me know what you have experienced!
