Offering copy-and-paste, Bluetooth tethering and A2DP - as well as performance improvements and MMS capability - the 250MB Apple iPhone OS 3.0 Software Update is the biggest update yet for the Apple iPhone 3G and first-generation Apple iPhone.

Security also gets a makeover on the iPhone OS 3.0 Software Update. MobileMe subscribers and Exchange 2007 users can remotely wipe and kill the iPhone if it is stolen, and backups can be encrypted and password protected through iTunes. MobileMe subscribers can locate lost iPhones from any web browser thanks to the "Find my iPhone" feature.

The update has improved performance, making everything from starting an app to typing on the keyboard feel more responsive. App compatibility is quite good, too; given the warning Apple provided to third-party developers, this isn't surprising.

iPhone 3.0

There is still room for improvement on the iPhone: Bluetooth file transfers and the ability to run applications in the background would definitely be appreciated, as would the ability to mark multiple emails as read in the Mail app. We were unable to properly test push notifications - Apple's solution for background applications - as third-party developers are yet to update their apps with this functionality.
