Here are the news of the 4S week-end.
The untether fails right now because I'm having processor cache issues.
I'm close, but I can't figure out what happens. It certainly has something to do with the Cortex-A9 cache management.
I could sort it out quick, it's a matter of chance.
I'll report you my progress tomorrow.
BTW: I removed (sorry) the greetings messages so that only articles related to the jailbreak remain in the main page. AFAIK Blogger don't have the option to move or fusion messages while keeping the comments.
