Apple have announced a special event on March 17th, where the company will launch the iPhone OS 3.0 Software. As usual, it has triggered a lot of speculation about what might be coming in the new release.

Mac Rumors cited Boy Genius Report that claims to have heard two most-awaited features: MMS (Multimedia Messaging Service) and tethering:

MMS would finally offer iPhone users the ability to send photos by way of SMS, and tethering would allow you to share your iPhone’s internet connection with your laptop computer. An alleged Steve Jobs email even confirmed that Apple had been working on a thethering solution, so it certainly seems feasible. BoyGeniusReport’s record, however, has been spotty, so we can’t be entirely confident of the report.

Mac Rumors also mentioned:

…a better app-managing SpringBoard (with categories?), a solution to “push” notifications (background tasks?), and, yes… even copy and paste…

Will 3.0 OS be available for the iPhone 3G? I hope so.
