Thank you. That worked and I can now access the home screen...although, sadly it looks as if all my data is gone.

I have a used iPhone 3GS that I've been using as an "iPod touch" for the last year or so. Last night I decided to upgrade to iOS 5. Now I'm getting the activation setup screens (which I wasn't expecting). I have since lost the SIM so I'm unable to activate it or do anything else with it. Any...
