So now that Apple’s iOS 4 is officially out, it was just a matter of time until Dev Team guys will eventually jailbroken it and make this platform even more available for everyone out there, especially those with iPhone 3G and iPod Touch 2G devices, who generally seem to be left out in Cupertino’s cold (3GS phones are not compatible with this one). At your own risk, simply download redsn0w 0.9.5 beta and start the installation process right away. Once finished, you can finally begin unlocking your mobile handheld, for baseband between 04.26.08 and 05.13.04, using Ultrasn0w 0.9.3 from the Cydia store. Be careful there, eh? If you need more help, just follow these step-by-step instructions on twittown.com.
Update: PwnageTool 4.0 has just been released as well, so you can now jailbreak your iPhone 3GS devices, in case they have the old bootrom installed, along with previous models like iPhone 3G versions and 2nd gen iPod Touch players. Once again, careful there.
