Each Apple ID can authorize at most 5 computers to utilize the DRM protection using that account. Though there is limit to Macs and PCs but there is no limitation to iOS devices like iPhones.

To deauthorize your application for example to deauthorize your computer in iTunes click on "Store Menu" in iTunes and select "Deauthorize your Computer…"
