trying this out right now but this guy says he got it to work
I had that same issue and I'm also using iTunes 7.6. However, I let iTunes activate my phone again which when I did the jailbreak using the .jar file, it took me back to square one. This happens if you don't click the eject button on iTunes. Basically at this point you want to downgrade back to 1.1.1 by getting the 1.1.1 firmware and clicking restore while either holding shift for windows or option for mac and starting the process over. Just make sure that once you click UPDATE again to update back to 1.1.2, once the process is completed, click EJECT in iTunes. If you don't do this, it will not jailbreak 1.1.2. (at least it didn't for me and I had to start over). Then run the jailbreak.jar file and let it complete the process. Once my phone rebooted, it was jailbroken with 1.1.2. Also, consider backing up your contacts by syncing it before you do the restore, otherwise you could loose em.
Here was the step by step instructions that I wrote this afternoon for anyone else who is confused. I tried it with a few friends who also had the same issue and it worked perfectly. I also updated the Wiki pages for anyone who is new and still has the 1.1.1 firmware.
As of today I was still running the 1.1.1 update for my iPhone. I wanted to update to 1.1.2 now that 1.1.3 was out and was just going to wait until the new update was jailbroken before I updated to 1.1.3.
1. Make sure you have the 1.1.1 firmware.
2. Make sure it has been jailbroken. Visit: www.jailbreakme.com from your Iphone and follow the on screen instructions.
3. Once the iPhone has restarted, open up the newly created Installer.app from your dashboard.
4. Click Install, go to Tweaks 1.1.1 and install the OktoPrep.
5. Download the 1.1.2 jailbreak software. Were going to need it in a bit: Click Here
5. Open up ITunes and download the 1.1.2 Firmware Here
6. Connect your iPhone and hold shift for windows users or option for mac users and click update.
7. Navigate to the downloaded 1.1.2 firmware file and click ok.
8. Let the iPhone reboot itself and when you see the Activate iPhone Connect to iTunes message, immediately click the eject button in iTunes. Failure to click eject resulted in me starting the process all over again.
9. Open up the jailbreak.jar file in the jailbreak 1.1.2 software we downloaded earlier.
10. Enable shell access if you want but click the jailbreak button. The software will go through a few steps and when your finished you should have a jailbroken 1.1.2 iPhone.
These are the exact steps I ran this afternoon and it worked perfectly. I never received any iTunes error.
