by: - Last updated on: December 17th, 2016

The iPhone Dev-Team has just released redsn0w 0.9.4 to jailbreak and unlock iPhone 2G. This comes soon after Apple released iPhone OS 3.1.3 which is a minor firmware update for iPhone 2G/3G/3GS, iPod Touch 2G/3G. Note that it is better to wait until iphone dev team update their tools to unlock and jailbreak iPhone 3.1.3 firmware if you have iPhone 3G/3GS or iPod Touch 3G or 2G (newer models).

But then, the newly released redsn0w 0.9.4 can be used to jailbreak iPhone 2G 3.1.3 along with iPod Touch 1G and iPod Touch 2G. 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.
