Verry simple way to downgrade Iphone 3G from OS 4.0 to 3.1.3

[Techgsmnet]

First , make backup of your data , then :

1. Put Iphone in DTMF mode
2. Using last Itunes 9.2, restore your firmware with 3.1.3 from here
3 .First to finish Itunes give 13 or 14 error and put your Iphone in Emergency mode, dont worry , is normal
4. Use iH8sn0w - iREB V3.1.2 , and your phone go normaly again in update mode .
5. Use spirit to jailbreak

Enjoy your Iphone with 3.1.3 with 05.13.05 firmware modem jailbreaked.
