My_Working_Books_8SB_.ipd. It's found in a file that contains a bunch of SB's at [Only registered and activated users can see links. ] ...MMS (Picture messanging) works, BBerry Maps Works which allows all GPS to work, and the Browser works.

Only things that don't work (I have a good amount of apps) are Facebook 1.6 and Crackberry App Store apps. That's ok.. just use the mobile web versions and your golden. Downloading Apps OTA (Over The Air) does work. Of course the Blackberry App Store and Blackberry email will not work as we are not paying for those BBerry services.

Other Apps That Work flawlessly to my knowledge. (I am not a super user so I didnt look deep into all functions of all my apps yet.. I am pretty sure all is working though):
Poynt, Weatherbug, Textender, GMail, Quickpull

Opera v4.2.14912 always worked but is weird.
Doesn’t use surepress interface. Maybe I am using the wrong version. Just gently touch the screen and you select whatever your finger just touched.. even if you don’t depress the screen to the point where it clicks. I dont like Opera. The BBerry Browser is a lot better in my opinion
