Any way to run with phone without getting it wet from sweat?

[volcs0]

I got an armband holder for my phone, and I really like the way it feels and fits. But I just got back from a long run in the heat, and there was a ton of condensation inside under the plastic, and the armband was soaked. I took the phone out, and it was very wet - there was even some condensation under the screen. I think it is going to be OK once it dries out.

I really like using RunKeeper, but I can't imagine a holder that can keep a phone dry and cool at the same time.

FWIW, this is the holder I got.

Any suggestions?

Thanks.
