MYSTERY ZILLION

I have upgraded my iPhone 3GS firmware a few days ago.
Before upgrading, I did a back of iPhone via iTunes. But unluckily after upgrading it, I cannot restore my application, contacts, photos ..., at all.

So I search it on internet and I found a discussion here.

But the discussion cannot help me to get back my photos.

Any body can help me about this issue.
Thanks in advanced.
