iphone 3.1 Triple Click Home for Accessibility Features

Speaking of iPhone 3GS accessibility features, it looks like Apple is improving them in iPhone 3.1 Beta 2 by adding a new "triple click" option to the home button to toggle VoiceOver, Toggle White on Black, and Ask (which then will pop up a menu offering Turn VoiceOver On, Turn Zoom On, Turn White on Black On).

Kudos to Apple for not only doing a great job implementing the various accessibility features in iPhone 3GS, but for continuing to improve them via forthcoming firmware.
