I have a percussion table mounted to my hihat stand where I place things like that (metronome, mini mixer, headphones, etc).
Alternatively, Gibraltar makes a clamp that's specially designed to mount things like mp3 players and phones to your kit:

Gibraltar one looks good.
Thanks for everyone's input.
If any wanna share more, please do.
Appreciate all suggestions.
I saw this video on youtube, it looks like a drummer/engineer invented one because he didn't like any of the phone/ipod mounts that he used. It also lets you mount your phone to a bunch of other places. Kind of cool...

He is also on Kickstarter selling them: http://kck.st/M5F5Sr
