No, I just looked on the android market and could not find anything dealing with iTunes. The iPhone is the only phone that offers iTunes. Apple is very strict when it comes to there products. They don't like to share. I hope this helps.
No, itunes on phones is strictly limited to iphones only. Each phone network usually offers it's own form of mp3 music, however. For example, verizon wireless has "vcast" for their mobile phones, and itunes for the verizon iphone4.
