The confusion of Grace Note’s Blu Ray support in iTunes was solved by beta who stated that iTunes incorporates Video ID which will allow consumers to flip between the files through their cover art and other information. This, however, doesn’t mean that Blu-ray support is coming in iTunes.

Apple was gradually preparing its application before launching iPhone 3.0. apple had announced the release of iPhone 3.0 in March. The iPhone software, currently in its beta version introduced several consumer oriented features that includes copy-paste, multimedia text capabilities and universal search function. Further, the upgraded iPhone will allow in-app purchasing, peer-to-peer multiplayer capabilities, and apps with third-party hardware. The additions will open up new vistas for more innovative and productive iPhone apps.

In 3.0 operating system we can cut copy paste text is one of the new option .there is a button which will help us to do so .This button have two arrows this button will  reverse text on just one click .not just this you can also undo action just by shaking .

The other option is to right your own review on an song which you think is your favorite songs or podcast.although this feature is not available for iPhone .Right now, people with the OS 3.0 beta installed can only read the reviews, but not make reviews of their own.This will be fully accessible when the OS 3.0 is released.

Apple will make us wait all the time until June / July to get this OS 3 hands on. It is expected that the New iPhone hardware and OS 3 would release on the same date!
