As of Devise 1.2.rc (see, you can make your devise users' emails case-insensitive by changing config/initializers/devise.rb to use:

config.case_insensitive_keys = [:email]

This works for forgot password, sign up, sign in, etc.

Replace :email with the authentication key that you use.

If you need to find a user (for example in a custom sessions_controller), note that User.find_by_email(params[:email]) is case sensitive. Use User.find_for_authentication(:email => params[:email]) instead.
