UnLimTones
 

If you iPhone is jailbroken, Unlimtones is an app definately worth checking out.
It allows you to download ringtones straight to your phone for free. Nothing special you need to do, just download them and they are there in the ringtones. You can preview them before DLing.....It's still pretty new and tones are being added to it everyday.

There's also an app called unlimmovies....it says you can watch full movies and TV shows and such...but all the ones I tried watching kept freezing on me.
I will continue to test it for the next couple of days and share the results.
