I updated the Joystick script that uses Notification Center for use with the new GUI setup in 4.6 beta.
Set up switch out the old joystick scripts and add this one, you can leave the one attached to the player alone. As, this will still output the same for position. You will have to add a background button image which doubles as the size and hit zone for the touch pad option.
//////////////////////////////////////////////////////////////
// Joystick.js
// Penelope iPhone Tutorial
// Moded by Hillary J. Ford for use with the new GUI system
// in Unity 4.6
// Joystick creates a movable joystick (via RectTransform) that
// handles touch input, taps, and phases. Dead zones can control
// where the joystick input gets picked up and can be normalized.
//
// Optionally, you can enable the touchPad property from the editor
// to treat this Joystick as a TouchPad. A TouchPad allows the finger
// to touch down at any point and it tracks the movement relatively
// without moving the graphic
