Apple announced the latest upgrade to iPhone OS 3.1 – firmware version 3.1.2 early last week and if you are waiting to jailbreak iPhone OS 3.1.2, the sad news is that the iPhone Dev team is yet to release the Pwnage and redsn0w tools. But the good news is that, if you are waiting to jailbreak your iPhone, GeoHot has just released BlackRa1n, which will allow Windows users to jailbreak their iPhone with OS 3.1.2.
