Thank you all very much for the feedback on this, I wasn't aware of the negative impact the viewport resizer was having on these mobile devices. It is to be expected that iframes would perform poorly on them and I had included a regex to redirect mobile user agents to the home.html page to avoid them having that served up. Perhaps the mobile device detection needs a more reliable method... Any suggestions? :)
