Iphone Dev Team Still Trying To Unlock 3G
Well posted on their blog is some bad news. Their new pwnage tool about to be released will activate and jailbreak the new 3G but it won't unlock. You guys are going to have to wait a little for that.
On a more positive note if you have a first gen iphone with the 2.0 software, it will be able to unlock that.
Apparently the latest build of firmware on the 3G is giving them some trouble and they want to wait until they perfect it.
