Many of you have asked about the iOS 4 Jailbreak and now we have come across some great news about PwnageTool Jailbreak for iOS 4.

Thanks to geek.com they have some news via the Dev Tem announcing the official release of the latest version of the Apple operating system and that it is now ready for download.

Apparently it is very hard for iPhone 3GS owners and is recommended to resort back and restore to a custom ipsw file created by PwnageTool 4.0 via DFU mode.

We recommend you visit Dev Team, you can try and run the PwnageTool 4.0 yourself and see how you get on, as usual we always recommend you backup before you install any such program.

Once you successfully jailbroken the iOS 4, you can then go back onto carrier unlock through ultrasn0W, it is totally up to you if you wish to try out the above. Please do not blame the messenger (US at phonesreview.co.uk) if anything drastic happens. If you have tried the above please let us know how you got on, thanks.
