I received my new Nook yesterday and picture my chagrin when you I realized you have to have access to a Wifi connection to register the darn thing. Well I took it to the library but there you have to log in via the web so that was a no go. Then I remembered, I could use my smartphone (A Samsung Galaxy) as a Wifi Hotspot. Now I'd never used it as such before but I held my breath and hey presto, it worked! I also tried it with my Kobo Touch and it worked with it as well. So that's my tip for the day. If you don't have a Wifi connection but own a smartphone? Check it out, you may be in luck
