Their is no 4.7 update for the 8130.
A battery pull will fix the camera issue, I've see it a few times..
On a MAC I don't think you can update the OS on your phone.
What is the "new issue"?
8830 -> 8330 -> 9550 -> 9650
Just think about how far BlackBerries have come from then till now... And what else is coming.
