Why does my phone keep forgetting the Default apps? Am running CM 7.2 on a Nexus One. Have tried resetting defaults with "Default App Manager," but eventually no matter what I do, my device forgets the Defaults for my Browser, images, music, SMS, etc... Is there a way to fix this permanently?
Normally there're four reasons for default apps to reset. 


You install an app that can handle that intent. 
You uninstall an app that can handle that intent. 
You update an app that can handle that intent. 
The app is on the sdcard and you rebooted/mounted it on a pc.


The fourth is commonly overlooked. Without source level changes this can't be modified.
