Ok i only have an ipod touch but I think that this will work the other way too. If you want to have two apps (videos and music) instead of ipod do this:
Go into ifile and go to /var/stash/applications click on MobileMusicPlayer.app and edit the info.plist
Next find a line of text that says :
<key> unified-ipod </key>
<false/>
and change it to true (note this is about 3/4 of the way into the document)
now scroll down a little more till you find the same thing as before but it says true and change this one to false.
save the plist and respring
