Can someone tell me if it's possible to use face time on my mac book pro after this update? Alss Icloud?
Yes to both questions. FaceTime is bundled with 10.8.
can i use facetime if I upgrade from Mac Os 10.8 to lion?
Your question is backwards, we must assume that you want to upgrade from Lion to 10.8.
Just to make sure the designations are clear so as to avoid confusion:
Mac OS X 10.6 - Snow Leopard
Mac OS X 10.7 - Lion
OS X 10.8 - Mountain Lion
10.8 Mountain Lion is the newest release of OS X.
