Have you tried downloading the update thru iTunes?

Are you on a fast Wifi connection? I'd not try it through 3G.

I had the same problem on both my iPhone 4 and my ipad 2. I tried this fix -- Can?t update your iDevice OTA or using iTunes? We have a fix

It worked for my iPhone but my iPad still won't download the update or update via iTunes. Weird.
