I plugged my iPhone into the computer for the first time today, since installing ios5.
Message comes up saying "unable to sync, need 20 gb of memory" or words to that effect.
What happens if I do a phone restore? Will I lose all of my contact info? What about all of my apps and music?

Can we fix it?
Yes we can!
