great piano soundfont found in iphone.

Still use iphone 3gs that want to change recently.

So had to backup before new one bought.

use ifunbox access the 3gs directly, i found some
piano apps use sf2 sound font.

digging each folders and files related,
i found a file called "Steinway Model L Grand Piano.sf2"
size 203mb.

Just let musescore 1.3 and updated tester version load this sf2 file.
Sounds improve too much, very high quality output to wav format.

I usually input violin & piano classical scores, seems like real grand piano playing around.
