So how do you know if you know how many users are accessing your website with an iphone?, Luckily most analytic packages will let you drill down and see the operating system and browser type.

From Google Analytics, its Visitors > Browser Capabilities > Browsers and OS.

A very small percentage are accessing using the Safari/iPhone combo, but Wii, PS3 & ipod touch visitors make up roughly 10%, so enough to warrant some configuration.

Accessing my site with an iphone looks like this, which doesn’t render too well as the width is too much and doesn’t zoom correctly.

Adding the WPtouch plugin, sets a mobile friendly theme for iPhone, iPod touch, Android, or BlackBerry Storm, with support for the following user-agents: android, aspen, blackberry9500, blackberry9530, cupcake, dream, incognito, iphone, ipod, opera mini, webmate, webos.

Once installed it looks like this to mobile visitors.

Very easy to install and configure, but makes a massive difference – definitely one of the must have additions for wordpress users.

(I’ve used a mac app called Iphoney to test)
