I too would love to see this done,Have any of you tried an OTG cable to try and connect it to the phone?I seeing a few ppl connecting their ps3 remote (wired) to other devices and able to play.I dont know if ours has the hosting capabilities for it though.
I might make one or just buy one and wait for it to see if it works
