Apple is set to officially unveil the iPhone 3.0 OS tomorrow, although they won't be releasing it yet. Rumors are flying about what's under the hood of the new OS. The biggest rumor is that the new iPhone software will include the much desired copy and paste function.

During a live taping of Diggnation, Kevin Rose gave some hints at what is inside the new OS. Interestingly, video recording and multi-tasking are expected to be left out of the iPhone 3.0. What's up Apple?

Stay tuned tomorrow for the official announcement.
