4.2.1 Jailbreak

In November, Apple approved an update to their mobile operating system iOS. Shortly after, the iPhone jailbreaking community hacked it. However, the only hack available was a tethered jailbreak.  Meaning when you reboot your device, you have to tether it to your computer which can be a pain. Now the Chronic Dev Team has released a new jailbreaking tool called greenpoisOn which  finally gives us the untethered jailbreak we’ve all been wanting.

Jailbreaking, is the process of hacking a mobile device to lift the restrictions put in place by the software maker or manufacturer. People jailbreak their iPhones (and iPod Touches and iPads, too) to install applications unapproved by Apple, to use their phone as a WiFi hotspot, to customize the interface and to customize the phone to fit their needs. Unlocking is a process that allows a phone to run on another carrier’s network. For example you may want to unlock an AT&T iPhone to work on a T-Mobile network.  An unlocked phone must be jailbroken but a jailbroken phone is not necessarily unlocked.

The redsnow software, developed by iPhone Dev Team, would work on both Mac and Windows machines, but as we stated earlier, it requires tethering to a computer every time it is rebooted. This is one, you probably want to look over, its a mess.

The new jailbreak, greenpoisOn,  will allow you to jailbreak without the tethering requirement. It’s currently only available for Mac users so PC users will have to wait just a bit. Looks like they are working on a Windows and Linux versions now. GreenpoisOn does not support unlocking so beware if that is a big part of why you are jailbreaking. The jailbreak supports the iPhone 3GS, iPhone 4, the iPad and iPod Touch 2G/3G/4G.

As word of warning many are reporting issues and some are even saying that the jailbreak doesn’t work. Some others are saying it took few times before the process loads as designed. Others are saying they don’t have issues at all. Bottom line, try it if you are dying to but you may want to wait a bit for the kinks to be worked out. If you have already jailbroken your phone with this software, leave a comment and let us know how installation and usage has worked for you.
