HELP...!! Another iphone3 stuffing up case.. sorry all..

Hi all, any help or advice to get this phone sorted out is greatly appreciated.

So it just blacked out on the screen (don't know when or how) but still has that little round icon circling. I've had the phone jail broken a while back and this has only ever happened once in the first week I got it back.

I got a heap of info and apps i really dont want to lose nor can I afford to lose..!!

If anyone knows how to resolve this problem without me losin
g anything of my phone, then id really like to hear from you.

Thanks everyone,

Andrew
