Some methods were made obsolete in Unity 4. They still work, but throw a warning.
This update fixes those warnings in these actions:
ActivateGameObject
Blink
DevicePlayFullScreenMovie
DeviceVibrate
Flicker
GetIPhoneSettings
GetLocationInfo
StartLocationServiceUpdates
StopLocationServiceUpdates
There's also a bug fix for GUILayoutBeginArea ignoring the style.
We're working on a bigger update, but I pulled these out to get them out quicker...
