My friend jailbroken his touch and and he added an app that allowed him download free music and apps. I really don't know much, but I guess it is called iPhuck?

I am not sure of such an app but it sounds like it is pirated music. As for apps that would be installer. iPhuc as you are talking about is a program, which I personally have never used.

i guess it is called the SendFile app. Does anybody know any information on this or where to download this? Is this even the right app?

We don't discuss or provide link to software that violates copyright.
with that said, I don't mean that your friend did because his music could actually be free.
My best advise it to ask your friend and use your best judgement.
BTW, i have no idea of what your friend is using.

Please ask your friend about this software.

"Free musics" are free because their authors decided so.

Music in general is not free.

Compositors/Authors/Musicians are working, it is their job !

The software you are talking about is downloading not free and copyrighted musics.

If you want to talk about piracy, please do it somewhere else.
This forum does not condone it, thanks.
