This method has been tested and works with iPhone OS 1.14 thru 3.1.3 and on all iPhone models (2G, 3G, 3GS) not tested on iPod Touch, but should work.
HAS NOT BEEN TESTED ON ITUNES 9.2 OR Apple IOS4 (CURRENT VERSIONS)
**WARNING– Unlockers WILL LOSE carrier unlock with this method if they update to 3.1.3 or 4.0 in iTunes!**
*Try the following procedure at your own risk, you WILL lose all your data (music, photos, high scores, etc.. ) with this method but will have a working phone again. You just need to re-sync with iTunes to get your apps, songs, movies, etc.. back after your phone is fixed*

I’ve found from much trial and error that having too many iPhone “official” 3rd Apple App store apps installed when you try to jailbreak the phone may sometimes cause the phone to hang up in a state of constant reboot.
Although I can’t and don’t guarantee this will work 100% of the time, if you’ve tried to jailbreak your iPhone and your phone gets stuck at the Apple Logo and reboots every 5-10 minutes, you need to follow these steps:
Setting the iPhone to recovery mode allows you to perform firmware restore using iTunes.
1) Power off the iPhone by depressing both the sleep/wake button on the top of the iPhone and the home button. Wait for the iPhone screen to turn black aka screen-off.
2) Depress the home button and connect the iPhone/iPod sync cable into the docking port on the bottom of the iPhone at the sametime without removing pressure on the home button.
3) You should be able to see the Apple logo coming up on the iPhone and then the recovery screen with be shown after the Apple logo:

4) iTunes will start and inform you that it has detected an iPhone in recovery mode and you should restore your iPhone to start using it.
5) Perform your firmware restore.
6) Exit iTunes and Re-jailbreak. I highly recommend using Spirit jailbreak but you can use, Pwnage Tool or BlackRa1n (or whatever jailbreak tool that will work on your model iPhone). Run the jailbreak app again and everything should go fine. Spirit takes about 3 minutes to jailbreak a 3GS and about 5 minutes to complete an older model.
7) Don’t restore from a backup, just set up your phone as a new phone, then re-sync to add back all your data and apps.
DONE!
ONCE AGAIN, **Unlockers WILL LOSE carrier unlock with this method if they update to 3.1.3 or 4.0 in iTunes and I can’t guarantee this will work 100% of the time, also I am not responsible for any lost data or a bricked phone or anything other problems encountered from trying this method. Try at your own risk, leave a comment and I’ll try to help out with any issues.
