A massive air drop of pre-loaded ipods and Go Phones over Tehran should do the trick.
I-Pods are way too fragile. Most would probably not survive a chute deployement or landing.
During WWII we air-dropped into France packages that contained small, stamped, single-shot .45 pistols that came with 4-5 rounds of ammo in the butt. They also came with short-wave radios that were powered by a hand-crank like todays "survival" radios.
If revolution is to happen in Iran, that is what they need instead of I-Pods. A palm-sized pistol that you can stick in a guys gut. Once he is down you trade up to whatever weapon he has on him.
If every cop or mullah in Iran has to to fear being shot in the face when he stops to harrass you about the hem of your skirt, or the length of your beard, then change will occur.
The means to resist is required.
