Apple today introduced version 3.0 of it’s iPhone software.

Forget cut and paste – here are the real reasons to get excited about Apple iPhone Software 3.0:

1. iPod Library Access – iPhone applications will have the ability to access the iTunes/iPod music library on your iPhone. You know what this means – iPhone DJing is going to get serious!
2. Stereo Bluetooth A2DP audio – You will be able to pair your iPhone 3.0 with a stereo Bluetooth A2DP device, like headphones or speakers, and stream music wirelessly.
3. Peer-to-peer Wi-Fi connectivity. A new API will allow for two iPhones to connect directly—peer-to-peer—via Wi-Fi, without needing any Wi-Fi network. Look for developers to use this to sync virtual instruments, wirelessly.
4. Use your iPhone/touch to control peripherals. A new API will let you use your iPhone or iPod touch as a control to your accessories. Want to control your gear with your iPhone? Now there’s an easy way to do it. Want to build a new iPhone-controlled instrument? Apple’s got you covered there, too.
5. Audio recording. Audio recording will also be possible from third-party applications using a standardized API, instead of custom workarounds. This means that you’ll be able to record and sync audio back to your computer without jumping through a bunch of hoops.

While the announcements weren’t as sexy as some Apple introductions, they are adding a lot of new options for developers – which means there are going to be a lot of cool new music apps, and accessories, on the way.

Update: CDM’s Peter Kirn is less enthused about the announcement, noting:

• Sync is still iTunes-only: Access to your library of your own music is a good start. But it’s only available to apps. What still isn’t available: any kind of sync API for getting your own files to and from the device.
• Peripherals suffer from reinventhewheelitis: What happened to standards for connecting hardware? On a computer, the ability to connect hardware and communicate to it is not news. On mobile devices, you’d think someone had invented some new technology – because they probably have, because hardware connections get reinvented each time there’s a new device.
• Hardware is still stuck with “Made for iPod”: Dreaming of a MIDI connector for your iPhone/iPod? My guess is, dream on. Apple requires proprietary licensing just to have the privilege of making hardware for the thing.
• Apple can still block your app. And sometimes they do it for no apparent reason.
