Planning on purchasing an iPod touch. If the 4G ipod touch still contains iOS4, I would have to plug the iPod in to itunes and follow directions to set it up? If the 4G ipod touch comes with iOS5, I would be able to set it up without iTunes? And add music and purchase apps at a later time? Dumb question but why is iOS5 not requiring iTunes to set up iPod touch where as all other previous devices needed iTunes to set up. Wouldn't people have to go back and transfer music from iTunes anyways. Is there a real benefit to setting up an iPod touch without iTunes.
