#ios 4.01

Just to remind you guys, while jailbreakme is compatible with all iDevices (iPhone/iPod Touch/iPad), it only works with iOS 4.0.1/iOS 3.2.1 and older firmware. This can’t jailbreak iOS 4.0.2 and iOS 3.2.2 since this new iPhone/iPad firmware plugs the exploit used by this particular iPhone jailbreak. This also isn’t compatible with beta versions of iOS 4.1. If you either have a new iPhone 4 with iOS 4.0.2 pre-installed by default or upgraded to the new firmware without saving your SHSH blobs first, here's a trick that might allow you to downgrade to iOS 4.0.1 thus allowing you to jailbreak your iPhone via the JailbreakMe website. In a nutshell, you just have to slightly modify the official iOS 4.0.1 ipsw file, and then transfer all the contents to the iOS 4.0.2 ipsw file. This will allow you to fool your iPhone 4 and iTunes into believing that it's installing iOS 4.0.2 while the truth is its iOS 4.0.1. Apple today officially announced the next version of their popular mobile operating system, the iOS 5 which will be available to you iPhone, iPad and iPod Touch this July. iOS5 also introduced iMessage, Newstand, Reminders, multi-tasking gestures and Airplay mirroring (for iPad2).
