After insterting new sim card into i-phone, message says insert a valid sim with no pin lock to activate. I don't have a pin on my phone?

If so, you'll need to jailbreak it again. Otherwise, if you have a NEW sim card from att, you'll need to activate it via itunes.

Try to use other sim card in your iphone. If it still registers the same error, have someone checked it. Either go to electronic equipment repair shop.

Your iphone might need some tests.

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.
