An anonymous source has provided iLounge with a listing of small but notable changes found in the second beta version of iPhone OS 3.1. A new option in the Accessibility menu allows users to triple-click the Home button in order to toggle VoiceOver or the White on Black features on and off; VoiceOver has also received a practice mode for learning its unique gestures. When editing video, the “Save” and “Save as Copy” options from beta 1 have been changed to “Trim Original” and “Save as New Clip” for clarity, and another change—possibly included in the first 3.1 beta as well—keeps the user’s “Now Playing” queue intact across syncs, meaning the user must manually change the playlist or finish listening to the one started prior to the sync. The other big change on the developer side is that developers can now monitor/debug their apps over Wi-Fi rather than having to use a USB connection. iPhone OS 3.1 beta 2 is available now to registered iPhone developers; Apple has yet to set a release date for a broader launch of the update.
