Apple's just confirmed iPhone 3.0 firmware is already rumored to add MMS picture messaging and data tethering. Also, Sirius XM has said it plans to give its radio subscribers an iPhone app, and Maine is negotiating a major deal to lease 100,000 MacBooks for its schools.

Possible iPhone 3.0 features leaked

While Apple has only just said it will introduce iPhone 3.0 at a special event next week, rumors have already surfaced of what the major refresh of the mobile OS will bring.

Well-known technology insider Boy Genius said he has been told of two new features so far. Notably, iPhones would get Multimedia Messaging Service support, or MMS. The standard is used to send photos and videos in a form similar to text-only SMS and has long been popular for trading content between phones for several years. Apple is one of the few phone manufacturers to leave out MMS.
