I know I have seen a few questions on here concerning a remote for the PS3 and I found this......

I have that remote but don't use it, I bought this Nyko Blue Wave, then used it to train my Logitech Harmony to control my PS3, the only thing it can't do is turn the PS3 on or off.

Also programmed my Harmony w/ the Nyko. Good $20 solution.

I have them both. The B/T remote works wonderfully, but it just added one more remote to a collection. I now use the same one these guys do so I can use my programmable remote – MX 850.
