I ran into this to the point where I got irritated and literally nuked everything off of my 32gig iPhone4. I finally decided to surf twitter and found an interesting tweet:
"Try turning airplane mode on, then off, then turn wifi on, then off, then turn airplane mode off and try updating".
Damned if my phone didn't update to IoS 5.
It worked for me.
