New Guy with a New Problem

gsm jb iphone4s on 5.0 w/1.0.11 firmware.


I cannot access my camera roll.
When I click on pics, camera roll pops up, when I click on camera roll it goes back to the springboard.

If I click on camera, then try to click camera roll, (lower left), back to the springboard.

So here's where is gets really weird, I click settings/general/about to have a look at the pics and vids, the number is crazy high for both pics and vids.
2,147,483,647
(that's 2 billion one hundred forty seven million four hundred eighty three thousand six hundred forty seven, if ur writing a check).

What the heck happened, and how can I fix this without upgrading to 6.0.1 and losing my beloved jailbreak?

Anyone ever hear of such crazy nonsense?

I have performed a hard reset on it several times with no success.
When I plug into my pc or laptop, my computer no longer recognizes it as a storage device, (although fortunately itunes sees it).

Any way to download the camera roll down to local, then delete all pics and vids from camera roll using itunes?

thanks in advance, I really need the video function for tomorrow's hs football playoff game :)
