Regular visitors to the uncharted backwaters of the unfashionable end of the Internet that is my blog may be aware that I use WordPress as a blogging platform. Those visitors who come here via a browser on a phone may even be aware that WordPress automagically presents a mobile friendly version of the site. This magic happens because of the user-agent string your browser sends to the web server hosting my blog; this string tells the web server what sort of browser (and more importantly what sort of device) is trying to view my blog. If WordPress sees a user-agent string like this …
Mozilla/5.0 (Linux; U; Android 2.2; en-us; Nexus One Build/FRF91) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1
… it knows that I’m browsing from my Google Nexus One and serves up the mobile version of the site, but if it sees a user-agent string like this …
Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_6_6; en-us) AppleWebKit/533.19.4 (KHTML, like Gecko) Version/5.0.3 Safari/533.19.4
… it knows that I’m browsing from Safari on a Mac and serves up the normal version of the site. Actually it’s not WordPress that knows how to act on a browser’s user-agent string, it’s a neat WordPress plugin called WPTouch that does the magic.
But then I tried viewing my blog on my new Windows Phone 7 handset and WPTouch doesn’t work its magic.
It turns out that there’s a clue to the solution in the name; WPTouch was designed to serve up the mobile view of a WordPress blog for the iPhone and the iPod Touch. Support was then added for Android and Blackberry handsets, but not for Windows Phone 7. Luckily, the plugin supports custom user-agent strings so adding support for Windows Phone 7 should be trivial. Well maybe not that trivial. A quick web search shows that there’s at least 10 variants of the Windows Phone 7 user-agent.
But rather than list them all explicitly, simply adding “iemobile“, the lowest common denominator, as a custom user-agent string catches them all.
Armed with all this information, my blog now support Windows Phone 7 with ease, plus adding “nokia, symbian” as additional custom user-agent strings means that my Nokia N8 can also view the mobile version of my blog.
As a final footnote, if you’re wondering why I’ve used photos of Windows Phone 7 rather than screenshots, it’s because along with multi-tasking and copy-and-paste, Windows Phone 7 doesn’t currently support taking screen shots. Yet. But then again, the original version of the iPhone lacked a lot of this functionality too, which did nothing to dent the uptake of that handset. Multi-tasking and copy-and-paste is promised in the next upcoming WP 7 OS update, hopefully with screenshot taking as well.
