mobility and prone

[Evilserran]

If I had mobility and stood from prone thats a move action, and i am moving in my opoonents threatened area, do i get the +4 from mobility?

No. It's a move action, but not considered 'movement' for most purposes, ie. you could still 5 foot step after standing. If you were to try crawling instead of standing, Mobility would apply (basically negating the +4 most attackers get against prone targets).
