For anyone that missed today’s major unveiling of the Apple iPhone’s 4.0 OS, we’ve got a quick breakdown. Some key enhancements to look forward to include the highly anticipated multitasking feature. The masses have been asking for it and now Steven Jobs and Co. will deliver. You’ll be able to run multiple apps at the same time, like using Skype to make a call and getting directions from TomTom’s GPS navigation app. You can run other apps like Pandora and check your email, without having to worry about the song going on pause. This feature will only be limited to the iPhone 3GS, while the 3G and Edge versions will be left out in the cold. Sucks for those guys.
