If you phone is NOT jailbroken, then the client files would have to be distributed on the app store (which wouldnt happen). Distributing these there would be warez, and open you up for legal action. Only sony may distribute the files.
If your phone IS jailbroken, then you are already in copyright violation according to apple. See:

Short of you getting an app in the app store that allowed you to sync to a PC and then install EQ to your phone via the discs its not legal.
So... like I said, wouldn't be legal, or would at least open you up for a lawsuit.
