Apple has released an update for the iPhone. The iPhone v1.0.1 update doesn"t add any new features, but does serve to plug up a few of the security holes that arose after the release of the device. iPhone users are encouraged to update as soon as possible to avoid possible security issues in the future.
Worthy of note, also, is the fact that users who have used software to hack their device must restore their iPhone before updating to the latest software version. As of right now, it appears that most hacks can be reapplied once the software update is successful
