I tired to jailbreak my iphone 3gs today. I downloaded black ra1n..... then i ran snow,rock, and cydia.... then i tired to tether it. I followed this page: http://www.mobilecrunch.com/2009/11...ther-on-an-iphone-3g-or-3gs-running-os-3-1-2/ I couldnt get it to tether so i was going to restore it.... but Itunes wouldnt pick up the phone. I tired the forced reset, put it in recovery mode but nothing worked. in recovery mode, Itunes recognized the iphone and tried to restore it, but it never finished and kept saying "unknown error occurred (1604)" now when i restart it just black or says on the screen with the itunes usb picture. I dont know what to do, help.
