Here it is.......
The back button does not work......
You can have both the All People and original My Favorites but they will have the same icon.
If you want to hide the original My Favorites tab go to:
HKLM\SOFTWARE\HTC\Manila\Configuration\ figure out which one of the numbered folders says Title: My Favorites and change the value of the key Enable to 0. Can't cab this part up because depending on your tab order it is diffrerent for everyone.
If you want to be able to move the tab around in customize tabs, do the reg edit (configuration) attached below. Rename .txt to .reg and import using reg editor. Soft reset and you will be able to customize where it is located in the tabs.
