Played around with one of these at home last night. Bluetooth remote paired perfect. Original IR commands from prior versions works perfect. The bottom pops off with a spudger just like the v. 2/3 so stuffing the IR emitter inside was a breeze still. The swipe on the new remote works good. What I wasn't able to do, yet, was pair it with my iPhone "Remote" app like I did with the 2/3. I didn't see an option for that in Settings...may have to do this via iTunes?
