if u have Titanium Backup you can move apps back to phone. Ass for moving to SD card there is NO need. the DroidX is one of few phones that have 8gb to use for apps. and that is all that it is used for. think of it like this some one has mounted 8gb SD card to the phone. It will not affect performance of phone it makes apps run better. but there is a catch some apps do require a real SD card those apps just store minor data and images for cache purposes. one app I'm particle is beautiful widgets. also I have 312 apps on my X and it barely made a dent in my storage space. when folks moan about size of apps we don't have nothing to worry about.
