We have been working on a mobile site for our virtual tours and we are just about there. The mobile site has been tested on iphone, ipad and Android phones (2.2 and higher). Please take a look at the site on your mobile phones and let us know what you think.
Next, we will be working on the best way to attach the QR Code (see below) to the for sale sign so that home buyers can just scan the code with their phone and then the mobile web site can be viewed on their phone (no flyers needed!) 
Just scan the QR Code below with your phone!!
