In order to give mobile users more control of how they view the site, your device will no longer be auto-detected by the site. If you visit the site url you will get the full PC version.
If you want to browse with a mobile device you should use either of the following links:
An iphone friendly site (this will likely also work with other devices that are similar such as the Droid as well as others I am sure):
http://iphone.502streetscene.net/
Mobile site for slower connections and devices with smaller screens:
http://m.502streetscene.net/
Once you use one of these URLs you can simply bookmark them on your device.
In the iphone version there is a link at the bottom to take you to the full site if you so wish.
Hopefully this is the best solution for everyone.
