redsn0w 0.9.4 to jailbreak and unlock iPhone 2G, iPhone 3G (No unlock
for 3G), iPod touch 1G and iPod touch 2G (older Non-MC models only). Do
not update to iPhone 3.1.3 firmware yet if you want to preserve your
unlock for iPhone 3GS, iPhone 3G, iPod touch 2G (new models) and iPod
touch 3G.

This is because the new iPhone 3.1.3 firmware updates baseband to
05.12.01 on iPhone 3GS and iPhone 3G which makes it impossible to
jailbreak and unlock iPhone 3GS and 3G.




Follow the simply step by step instructions below to jailbreak and
unlock iPhone 2G, jailbreak iPod 1G/2G (older models only) on 3.1.3
firmware. You can also jailbreak iPhone 3G with redsn0w 0.9.4 but doing
so will make you loose your unlock.
Note: In this guide I have used redsn0w 0.9.4. If this version gives
you problem on iPhone 2G and iPod touch 1G, then try redsn0w 0.9.3.

Step 1: Update to original iPhone 3.1.3 firmware via iTunes.




Step 2: Start redsn0w 0.9.4 and point it to the respective

iPhone 3.1.2 instead of 3.1.3 because redsn0w 0.9.4 is still unable to
validate the latest firmware.

to quickly hold “Power” button and then while holding the “Power”
button, you will now have to hold “Home” button too. Now after few
seconds release “Power” button but keep holding “Home” button until
