For the other programs you can go to options>advanced>applications and delete from there or go to the application loader in DM (Desktop Manager) on your PC
kinda hard to search for specifics. im considering reloading my OS and deleting useless junk from device to allow more memory.
net_rim_bb_qm_google_resource_ar.cod may be useless. if so, someone can make a sticky and new memory for peoples devices. vcast is not "deleteable" so to say, but i wanna remove it from java files or whatever because ill never use it and want no part of it.
