Help with jailbreaking and Cydia for iPhones, iPads, and iPod touches.

I just spent 13 hours doing this on a 2009 3GS. The problem was the order of the procedure and setting the Base Band (BB) to 06.15.00. Warning: You have to make sure the BB is 06.15.00 (or another compatible BB listed on redmondpie.com) and not higher otherwise, you’re screwed.

1. Upgrade to 6.0.1 via iTunes UNLESS you have 3GS made after week 28 of 2011. There are many articles written about why this will brick your phone so feel free to Google those for an explanation.
2. List item
3. Get Redsn0w version 0.9.15b3
4. Download iPhone2,1_6.0_10A403_Restore.ipsw
5. Follow the jailbreak procedure here: http://www.redmondpie.com/jailbreak-ios-6.0.1-on-pre-a5-iphone-and-ipod-touch-using-redsn0w/
6. Don’t do the “Just Boot” thing yet (this is where I kept getting the missing keys bullshit)
7. Jailbreak the phone again using the same procedure listed before, but uncheck the “install Cydia” box and check the “install iPad Base Band” box and say you’re sure. AGAIN, verify this is what you want to do! If you have a late model 3GS, DO NOT TRY THIS! IT WILL BRICK YOUR PHONE!
8. Do not try to “Just Boot” the phone yet.
9. After the 2nd jailbreak, your phone will be on. Go into the Cydia app and install Ultrasn0w. There are plenty of articles written on this.
10. Go into Cydia app again and install Untrasn0w Fixer 6.0 NOT 6.0.1! Note: If you’re planning on using the iphone with T-Mobile, you need to turn off 3G in the settings on the phone. This goes for any network without 3G service.
11. Go back into Redsn0w and follow the “Just Boot” procedure.
12. The iPhone should reboot with a pwnapple logo.
13. Ta-Da!

Lastly, try to not turn your phone off. This is a tethered jailbreak so if you turn your phone off, you will need to boot up the phone via Redsn0w to get the jailbroken functionality again. I also repaired disk permissions a few times in conjunction with this jailbreak. I don’t know if that helped, but it didn’t hurt.

STOLE THIS FROM EddieUtah ON Gottabemobile.com PLEASE GIVE HIM CREDIT FOR THIS FIX.

The only change I would make to these directions would be after you do the 2nd JB and iPad BB install, tether boot it then or else cydia won't show up.
