Excited, downloaded and installed, yes I am talking about iOS 4.0 night(IST). So yesterday was the day you did this big download and has started enjoying 100 of new features on your Apple devices. Some might have stayed away from this update fearing, they might loose their jailbreak and the device will get locked. Your fear is over all thanks to iPhone Jailbreak team, they have launched their tools within 8 hrs of launch of new iOS.
Note: This only works on iPhone 3G and iPod Touch 2G as of now.
Step 1: If you have iPhone/iPod Touch running OS 3.13(not jailbroken) upgrade to new iOS 4.0.
Step 2: Download redsn0w beta ( This is still a beta version)
Step 3: Open redsn0w and select the iOS 4.0 IPSW that you used to upgrade your iPhone/iPod Touch
Step 4: Then select Install Cydia(mandatory) and other options are optional but they will eat up your battery and slow down your device.
Step 5: Then follow the on screen instructions to successfully jailbreak your device.
Step 6: After your device has been jailbroken it will reboot, after that switch on WiFi(preferred) and click on Cydia. Cydia will take quite amount of time to reorganize, reload and update itself. If asked do the complete upgrade inside Cydia.
