Just like your Honda Civic, every once in a while your mobile phone needs a little kick. The iPhone OS 4.0 is sure to take your smartphone experience to the next level. Recently introduced by Steve Jobs, the upgrade will be released for free later this year for Apple users.

Some of the notable new features that the iPhone OS 4.0 will bring to the phone: a better multitasking platform, the iBook app, a unified email system that lets all your accounts go into one inbox, and wireless app distribution among other features. The upgrade is expected to be released some time this fall.
