I have an iPhone 3G, it's running on O.S 3.0 it's jailbroken of course now, apple has released iPhone O.S 3.0.1 and it's jailbreakable but I'm not sure that all of cydia apps could run on O.S 3.0.1 since it's new should I upgrade? Reply please, thx
Yes you can upgrade using iTunes as you normally would then re-jailbreak using red-snow. When you jailbreak using red-snow select the iPhone 3.0 file rather than the 3.0.1 file.
