We covered that the hackers found several exploits over the last few weeks. These exploits help bypass parts of the system, however, seems those are not enough. P0sixninja, lead of Chronic Dev Team, just tweeted that the current jailbreak they are working on needs 7 exploits, two for the sole purpose of avoiding legal problems and 5 for technical handles.
Hopefully this is a sign that the jailbreak is near completion. According to Pod2g, an important kernel vulnerability needed to do a jailbreak came from a new jailbreak Nicolas Haunold -
@westbaer. For now, @pod2g is the last one who does iOS kernel exploits, it's nice to see a new hacker joins the jailbreak community!
We will keep you updated!
