YouTube showing on iPhone and Apple TV: If the ability to watch YouTube videos on the iPhone is all the enticement you need to drop a half-grand on one when Apple's much-hyped mobile launches on June 29, you're in luck. Apple announced today that the phone will be able to stream YouTube content wirelessly over Wi-Fi or EDGE networks. Apple TV owners have the same option today. To add this feature to your Apple TV, navigate to the Settings menu on the Apple TV's onscreen menu and select Update Software.

The iPhone's ripple effects: The iPhone isn't just a smartphone. It's a market driver - or at least it has potential to be. In addition to getting public love from Google CEO Eric Schmidt, the iPhone is expected to:

> Fuel a touch-screen bonanza

> Be just the beginning in a line of Apple mobile communications devices, including lower-end models
> Engender a huge line of accessories and add-ons
> Create new markets for mobile gaming and Safari-based apps
> Give a lot of Americans something to do besides having one too many at happy hour on the night of Friday, June 29
