The title has the question in it. If you have someone pinned, can you use them as a body shield, still?

Benefit: As an immediate action while you are grappling an adjacent creature, you can make a grapple combat maneuver check against that creature to gain cover against a single attack. If you are successful and the attack misses you, that attack targets the creature you used as cover, using the same attack roll. You cannot use this feat against a creature grappling you, and the cover you gain ends after the attack you gained cover against is resolved.
Preemptive rebuttal of the "pinning =/= grappling" argument...

A pinned creature is tightly bound and can take few actions. A pinned creature cannot move and is denied its Dexterity bonus. A pinned character also takes an additional –4 penalty to his Armor Class. A pinned creature is limited in the actions that it can take. A pinned creature can always attempt to free itself, usually through a combat maneuver check or Escape Artist check. A pinned creature can take verbal and mental actions, but cannot cast any spells that require a somatic or material component. A pinned character who attempts to cast a spell or use a spell-like ability must make a concentration check (DC 10 + grappler's CMB + spell level) or lose the spell. Pinned is a more severe version of grappled, and their effects do not stack.
And the "pinning means against the ground" argument...
The way PF describes pinning, no one is necessarily prone. Realistically speaking, pathfinder "Pinning" seems to be more along the lines of having someone in a full body lock--this can be done with you (the grappler) on bottom just as effectively as with you on top.
