Unity iPhone 1.0.1
Whether on an iPhone or an iPod Touch, you will be able to dazzle your audience with the finest content available in the App Store. 2D or 3D, touch or tilt — if you can think it, you will be able to build it.

Increased Performance
From changes to the default settings to the addition of iPhone script call optimization, this release is focused on helping to ensure that your games continue to redefine what gamers expect to find on a phone.

Improved Live Preview
Improvements to the reliability of UnityRemote ensure that all touch phases and accelerator changes are registered while viewing and testing your game inside the Unity Editor.

Compressed Audio
With mp3/m4a compressed audio playback, you can include longer playing audio files in your games without compromising your distribution size.

Additional Features, improvements, and changes
New Features and Improvements
Added support for compressed mp3/m4a audio playback. Note that iPhone hardware supports only one compressed audio clip at a time
Improved performance of script to engine calls by an order of magnitude (e.g calling transform.localPosition is 300% faster).

OnApplicationQuit() callback gets called while quiting Unity player
OnApplicationPause() callback gets called once Unity player becomes inactive
