We're just hours away from Apple's bells-and-whistles meeting where it will reveal the real deal on iPhone application development, and new information's beginning to trickle through.

Peter Oppenheimer, Apple's chief financial officer, last night told those at the Morgan Stanley Technology Conference that the company will talk about the iPhone in the enterprise.

Oppenheimer also noted that the frequency of iPhone unlocking reflects demand for the device, and echoed chief operating officer Tim Cook's comments last week in which Apple revealed it isn't "wedded" to its existing revenue-sharing deal with mobile operators.

"We're off to a great start, but we're learning and we're not wedded to any one particular way to go to market. Our objective is to drive scale and take market share," said Oppenheimer.

MacRumors warns that the iPhone SDK will be available for Mac OS X only and that the software will be made available as an extension of the capabilities of the Xcode development tools shipped with Mac OS X 10.5. This makes sense on account of the OS X system that runs iPhone.

Analysts are beginning to get categorical, too, with many now anticipating Apple will announce support for Microsoft's Active Synch technologies for the iPhone, meaning Entourage support, and the long-expected support for Lotus Notes, may appear.

Finally, whispers reaching 9to5 Mac from various closely-connected sources suggest iPhone users can look forward to "a few more" applications for their devices, perhaps as soon as today, but no word yet on what these may be.

That's despite recent conjecture claiming the iPhone SDK announced will be available as beta software only.
