Turn Your Zombie Phone To A Media Server

If you have a recent Nokia phone (C6-01, C7, E7, N8 and X7 are supported at the moment), you can turn it to a PS3-compatible media server by installing the Play To application from Nokia Betalabs. Don't forget to enable Media Server in Settings/Connectivity.

I couldn't make direct sharing work with the current beta, but browsing the phone and playing back content from the XMB is already possible.
