Jailbreak Iphone 3G by updating to IOS 4.0 GM. Apple had just released Iphone OS 4 GM candidate (note that Iphone OS 4 is now renamed IOS 4) to app developers and the dev team has already announced the ability to jailbreak Iphone 3G, if users can update to the seeded IOS 4 GM.
IOS 4 GM candidate is the shipping version of Iphone OS 4, that developers are supposed to use, to build applications that can run on Iphone OS 4. IOS 4 will be available to Iphone users i.e. iPhone 3G, iPhone 3Gs and iPod Touch users on June 21 for free.Users can then freely upgrade the OS on their Iphones to IOS 4.
But if you somehow manage to get access to IOS 4 GM candidate, then you can jailbreak Iphone 3G! with redsn0w. We had earlier told you about the availability of redsn0w 0.9.5 to jailbreak Iphone OS 4 beta.Iphone 3G users can now rejoice, as they can jailbreak their phones on IOS 4 GM candidate with rednsn0w.
According to MuscleNerd from Dev team (who has tweeted this trick), Iphone 3G users have to point redsn0w at the Iphone OS 4.0 beta4 IPSW instead of IOS 4.0 GM.This trick is called “point to previous IPSW” trick. However, Iphone 3G users will have to first update their smarphone OS to IOS 4.0 GM and activate it through the new iTunes 9.2.
It is important to remember that this will work only on Iphone 3G. It is also important to note that carrier unlocks aren’t yet supported at IOS 4.0.So you shouldn’t trying this trick if you use yellowsn0w/ultrasn0w/blacksn0w.
So if you have legitimate access to IOS 4 GM candidate, then go ahead jailbreaking your Iphone 3G and enjoy. Iphone 3G Users, who do not have access to IOS 4 GM, have to wait till the public release of full IOS 4.
Apple has announced a great new Iphone 4 and people are already dreaming about jailbreaking it as well.
