The following article will show you how to install firmware 3.0 on your iPhone 2G by also allowing to jailbreak, activate, and eventually to unlock (JAU process). At the moment of writing this article is for Mac OS X users with iPhone 2G’s only.
II. Who needs this article?
We suppose 50% of all 2G users around the globe. As iPhone 2G’s were sold almost everywhere with Sim-Lock enabled (besides some T-Mobile Germany or Orange France unlocked 2G’s).
You’d better read all of this in detail before you do anything practically! If you feel there is something you don’t understand or something you will not be able to handle, then go and ask someone who is in the know.
!!!!!!!! Otherwise your devices may be terribly screwed up! !!!!!!!
