mobile version not showing in safari

I use the safari develop user agent when working on the mobile version of my site. But since the update it does not seem to be working. Only the full version is display. This is really frustrating to me since I do a lot customization of the site css that using safari on my pc made much quicker. Did you change the way the component looks at user agents?

What is url of the site?

This is our QA site. I updated mobile Joomla yesterday. Before the update I had no problem seeing the mobile version when I change the user agent in safari. The mobile version does show up on my iphone but it is weird it does not on safari. I also clear my cache and cookies.

I just try it on another pc with an older version of safari and the mobile verison came up. So it must be my browser. Thanks for your help.

Works well in Firefox with UASwitcher plugin.

Note that the following "checks" have higher priority than browser's UA:
1. Mobile mode detected from device=??? parameter in urls.
2. Mobile mode that is saved in cookies and/or user's session data.

Visit www.mobilejoomla.com/uatest.php by safari with iphone's UA. What results it shows?
