Gen2 Ipod Touch as Squeezebox player

Hi Guys

I have an old Gen 2 Ipod touch and an dock and I was hoping to start using them as an additional squeezebox player in my existing system. I'm looking for an app similar to Ipeng or squeezecast that is compatible with the old IOS4.2.1 that the 2nd gen touch runs on.

Does anyone know of such an app that might be suitable for this situation?

Thanks very much for your help

Will
