How to JB 3.1.2 with Blackra1n on Windows!
As you guys all know the Blackra1n jailbreak by GeoHot was released a couple of hours ago. The jailbreak works on all the devices out there and can jailbreak firmware 3.1.2.
All credit for the guide goes to DigitalMarketingTalk.com.

•Downloaded Blackra1n.exe
Reminder: If your iPhone is unlocked via ultrasn0w then please stay away from Blackra1n. Blackra1n is for those users who aren’t worried about losing their unlock ability(moving to baseband 05.11.07). So, if you want to preserve your baseband do not use this tool.

10) Congrats you just jailbroke your iPhone using Blackra1n. Kudos to GeoHot!

Warning for Dev Team: Caution!
Geohot released a Windows jailbreak called “blackra1n” which is similar to redsn0w in that it covers multiple devices (and it covers beyond just firmware 3.0.1 where redsn0w currently stops). blackra1n is not a carrier unlock. You must always avoid updating your baseband to maintain your unlockability. If you use blackra1n to jailbreak 3.1 or 3.1.2, the steps you take before running blackra1n will prevent the unlock from working on your iPhone for potentially a very long time. By the way, we haven’t yet tested whether a blackra1n’d device can accept a custom IPSW without tweaks, but if it doesn’t then it should only require a minor change.
