Rails: Detecting user agent works in development but not production?

I am trying to detect Blackberry user agents in my app, which works fine in my development version. But nothing happens when I redeploy the app in production.

application_helper.rb

  def blackberry_user_agent?
    request.env["HTTP_USER_AGENT"] && request.env["HTTP_USER_AGENT"][/(Blackberry)/]
  end

application.html.erb

<% if blackberry_user_agent? -%>
<div class="message">
<p>Using a Blackberry? <a href="http://mobile.site.ca/">Use the mobile optimized version</a>.</p>
</div>

I've tried clearing the cache using rake tmp:cache:clear and restarted mongrel a few times. Apparently the HTTP_USER_AGENT is coming back nil in production. I am using Nginx with a mongrel cluster.

Are you using Apache or nginx in front of your mongrel(s)?

Are you logging the user_agent? This is from my nginx.conf:

log_format main '$remote_addr - $remote_user [$time_local] $request '
                  '"$status" $body_bytes_sent "$http_referer" '
                  '"$http_user_agent" "http_x_forwarded_for"';
