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.
Jailbreak iPhone 3.1.2 OS with Blackrain
Warning: The current update of Blackra1n only supports iPhone OS 3.1.2, do NOT use this tool if you are using an earlier version of iPhone OS. We have unconfirmed reports that BlackRa1n supports iPhone OS 3.1 as well, but we are not sure.
Also, do not upgrade to 3.1.2 using iTunes if you want to keep your unlock. Baseband cannot be downgraded.
Download Blackra1n for iPhone/iPod Touch
You can download BlackRa1n to jailbreak iPhone and iPod Touch OS 3.1.2:
Download blackra1n
Once downloaded, make sure to update your iTunes to the latest version.

Anyone tried to reboot your iphone after jailbreak, does it go into recovery mode which require iTune to restore?
Mine happens everytime I reboot. =(
Please can someone explain why my 3G nor Edge is not working. Does this unlock allow the use of Tmobile data plan??
Thanks in advance
If you have a 3GS Apple unlocked and running on 3.1.2, please do not jail break wih black rain. It screwed up my phone and I had to restore.
installed on my 3gs,all seemed good but i lost my wi-fi access??? maybe a coincidence…maybe not???
i downloaded blackrain it told me to wait for rebot then my touch shut off itunes said to restore before i can use it wat do i do?
i downloaded the program and tried installing it to my ipod touch 3.1.2 firmware and now it wont work it stays on the itunes plugin screen…. help me please =(
if you have the ipod touch 3g or i think iphone 3gs you just have to rerun blackra1n whenever you fully turn off your ipod. That is what I have to do with mine and you will still have all of your apps including cydia
Dont worry Delia, you can restore it and then again run same program, sometimes it just takes two or three tries. @thatguy – as the apple has upgraded the baseband of new devices we all have to rerun black rain; this is called as tethered jailbreak.

Shiva,
I have the same problem with unlocking and jailbreaking it using blackra1n. I had to restore it twice already. In order to get your iphone back to normal you would have to do a master reset. You can find the video on this website: http://www.youtube.com/outatimeoyster

I used blackra1n RC3 to jailbreak my iPhone 2G. The jailbreak goes great but when I open the Blackra1n app to unlock the phone I keep getting an error message about checking my internet connect and it won’t let me install Cydia so I can get BootNeuter to unlock the phone.
