I'm trying to do this update via iTunes and iTunes says it will take seven hours. Download speed is excruciating. I've tried again and again. Thinking it might be my connection, I did a speedtest and got 18mbps, which I think is reasonably fast. The whole download is something like 600 mb, so should take maybe 10 minutes. I'm using a Macbook Pro, a first gen iPad and Airport Express set up as a "roaming network" to bring the Internet out to my office from an Airport Extreme in the house. Anybody having a similar experience? Any solutions? Many thanks.
