touch pro 2 manila changes for pocket informant

[saecrow]

recently upgraded to touch pro 2 and am trying to get pocket informant to replace the stock calendar app. anyone know how to make it so that when i touch "calendar" under the clock on the home screen it launches pocket informant's calendar app? (also on the slider at the bottom?) i remember for the touch pro there was a cab / tweak that had to be done for the home screen (calendar wasn't on the bottom slider) and when i tried that cab, it didn't install successfully.
thanks!
