Adobe Labs' Shadow is an application for Mac and Windows that allows you to preview and inspect your mobile website on iOS and Android devices.

After installing the software on your computer and any number of mobile devices, you can connect and pair them and all devices will be kept in sync with the web site you're previewing on your computer. This should help perform remote inspection and debugging so you can see HTML/CSS/JavaScript changes instantly on your devices.
