I have a 3g on 3.1.3 jailbroken with spirit a few months ago. I want to update to ios4?

Yes Restore your iPhone to 4.0, and use either Sn0wbreeze (Windows) or PwnageTool (Mac) to jailbreak it.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
