Can I listen to my PC from my IPhone?

I can't listen to my laptop with headphone cause I broke my headphone jack I was looking for an app than can play the sound on my phone. I found one but it only works on for windows xp/vista/7. I'm hoping someone know another app or a different way?

Yes there are a few. The one I've used for some time is SoundWire. You need to install and run the SoundWire Server on your computer and download the app for your phone. There's a free and paid version.

Sound wire is a good one.
