iPhoneApple have tied down the iPhone meaning that no other software can be installed onto the device without it being approved by the Apple team and therefore means that some things are never going to get the ok.  This to me seems to be abit of a monolopy over the iPhone / iPod ranges by using the iTunes store as the only way to get things onto the system.  I assume that everything purchased from the store gets some money going into Mr Jobs pocket.

Not surprising along came jailbreaking of an iPhone / iPod Touch, this voids the warranty of the phone and is most probably illegal since its hacking into the iPhone software using illegal entry to allow it to run other applications.  Now on the one hand I can see that this should not be done because of the voiding of the warranty and the potential other risks involved.  But on the other hand I can completely understand why people do it because there is some very good software available for example mPlayer (linux media player), OpenSSH and a ftp server.

Looking at software that is available if the phone is jailbroken, there is a good one called SBSettings that allows the user to easily toggle Wifi, Phone, 3G and others all with a simple swipe across the status bar at the top.  The great thing about this is that it runs in any application.

So how does jailbreaking work?

Well its quite a “simple” process, using a security exposure in the software to install a piece of software.  This software then allows you to install a package installer.  The one of choice at the moment is cydia and this allows users to install unix style packages for extra functionality.
