A week ago at WWDC 2009, Apple announced version the public release of 3.0 of the iPhone OS, and whilst the new OS will offer....

• Cut, Copy & Paste
• Landscape Keyboard
• MMS
• Spotlight Search
• Voice Memos
• Improved Calendar
• Buy Films, TV Programmes and Audiobooks
• Enhanced Stocks App
• Safari Improvements
• Internet Tethering
• Stereo Bluetooth
• Automatic Wi-Fi Login
• Sync Notes
• Parental Controls
• iTunes Store Account
• YouTube Login
• Shake to Shuffle
• New Languages
• MobileMe Find My iPhone and Remote Wipe
• Run the Latest Apps

....to existing iPhone owners.

Whilst these new enhancements are welcomed, sadly there is nothing new for us iPhoneographers. I had hope that Apple would have given us the video feature despite the existing iPhone only having a 2.0 megapixel camera, but sadly they have decided against this.

So sadly the answer to "What does iPhone 3.0 bring to existing iPhoneographers?" is nothing.
