A Few New Functions Spotted in iPhone 3.0 Beta

The latest iPhone 3.0 beta has brought with it a few minor but notable features to the platform. Here's a quick rundown of the newly discovered functions:

Audio
• Variable speed track scrubbing
• Variable speed podcast playback (.5x and 2x)
• Single-button 30 second podcast rewinding

General
• Close all Safari windows at once
• Battery Indicators feature percentages (numbers, not just bars)
• Expanded data detection (phone is more apt to hotlink emails and numbers)

Those are just the details we found most important. There's more at all of the links (written by the guys who did all the legwork). [Wold of Apple and Apple Insider via Macrumors]
