Dear habrapolzovatel, here are brief instructions

redsn0w is a QuickPwn-style program. Before starting the program, flash the iPhone / iPod on the new firmware in iTunes. Run redsn0w and follow the instructions. Everything is very simple)

For 3g: After flashing and using the redsn0w utility for unlocking the phone, add repo666.ultrasn0w.com to the repositories of the sidia and look for ultrasn0w.

Dear habrapolzovatel, here are full instructions, but be careful - English
