How to get list of installed apps via iTunes? I need to know what applications are installed or were installed on devices which are associated with iTunes account. I don't have access to the devices. Is it possible?
You can see all purchases made through the iOS App Store within iTunes (on OSX or Windows):


Start iTunes
Log into the Store in the Store menu
Show Account Details (in the Store menu as well)
Shopping Statistics (don't know how it's called in the english version, it's the third block from the top)
