Several iterations of Pete's GPA series he included some sort of sound enhancement app in his ROM. For the life of me I can't recall what, exactly, it was called. I'd like to load it onto my D3 as I'm a bit hard of hearing and the enhancements to the 4k region seemed to help me hear better when I was in a call. Can anyone chime in and tell me what the heck that app was called? Thanks!
