iPhone 2G Jailbrek

Hello.

I have jailbroken my 2G iPhone before. Recently I changed sim card and erased all data on the iPhone. After jailbreaking it again to version 3.1.3, iTunes said something like "the Sim Card is not supported". To jailbreak I used pwnage tool. Please help!

If you are using a sim card from a different carrier than the phone was from then you need to unlock it too.

I thought i did that when i jailbroke it? If not, can you please explain to me what/how to do?

Jailbreaking is a process to make it possible to download and install third-party apps onto the iphone, i.e. apps not from the app store.
I won't go into unlocking it here but google around for "unlock 3.1.3", there are plenty of tutorials and walkthroughs with all the relevant download links and software to do it.

This month's issue of MacUser has a detail-packed article on jailbreaking including a full how-to guide, the pros and cons, etc.

He has done the jailbreaking, it's the unlocking he needs now.
