Connection timed out a couple of times while downloading iOS 5

Hi,
I need to find out what happened to my iPhone. While I was downloading the iOS 5 at a crawling speed yesterday, my connection timed out a couple of times. Then at one time, while my iPhone was re-authenticating itself on the Apple server, my connection timed out, the screen flashed “Error 3200″.

Please try again later.
What does this mean? Can anyone help me out.
Thanks.
