Before I picked up the Simply Rails book, I had been messing around with rails. I updated to rails 2.3 just for kicks, but now want to revert to 2.2 since v2 it is what the book is using.

I do the following

sudo gem update rails -v 2.2
>>Updating installed gems
>>GET 200 OK: h ttp://ge ms.rubyforg e.org/latest_specs.4.8.gz
>>Nothing to update
rails -v
>>Rails 2.3.0

I can't seem to return to version 2.2. Any ideas?

Thanks!
