Several video reviews of the iPhone OS 3.0 have been uploaded to the likes of YouTube, so that everyone can see Apple's new additions in action. Previewed in the video below are the highly anticipated changes for the end user, such as copy-paste, MMS, landscape view in different apps and more.

Apple has included with iPhone OS 3.0 over 100 fresh features like cut, copy and paste, which can be done within or across applications, MMS to send and receive photos, contacts, audio files and locations with the Messages app, and the ability to capture and send audio recordings on the go with the new Voice Memo app.

Landscape view will be available for Mail, Text and Notes, while the Search capabilities will be expanded to search within Mail, iPod and Notes or search across all key apps by typing a key word or phrase into the new Spotlight search – accessed from the Home screen.

An updated Stock app will add the ability to display recent company news and current trading information. For example, users will be able to see opening or average price, trading volume or Market Cap. Those running OS 3.0 will also be able to view shared calendars right on their iPhone (with CalDAV support), and sync their calendars with iCal, Yahoo, Google and Oracle, as well as read and compose email and text messages in landscape view.

iPhone OS 3.0 will be available to iPhone and iPod touch users this summer. It will be a free update to all iPhone users, while iPod touch owners will have to pay the usual $9.95 for the upgrade. Due to hardware differences, features such as A2DP and MMS won’t be available on the original iPhone, according to several sources. The developer beta of iPhone OS 3.0 is immediately available, accompanied by a new beta of the iPhone Software Development Kit (SDK).
