It's here the new version of IOS 4.2, 4.2.1 iOS specifically for iPhone, iPod Touch, Apple TV iPad and the procedure for making the jailbreak has changed, it is now necessary to make the Jailbreak with redsn0w but before it necessary to clarify 2 things:
- Cydia works not yet officially iOS 4.2, but there is a patch for to run on 4.2 Cydia
- If you want to free your iPhone to use it with any company then do not use redsn0w, Expected to be a safe method that allows you to Jailbreak your iPhone free
- Apparently this is a Tethered Jailbreak.
To make the Jailbreak your device iOS 4.2.1 need iTunes 10.1Here I leave the iOS direct link to download version 4.2 at its iPhone 3G, iPhone 3G, iPhone 4, iPad, iPod Touch 2g, iPod Touch 3G, 4g iPod Touch and 2G Apple TV.
