I’m using my phone quite a bit these days for mobile internet/bluetooth modem. Most sites I hit show full web pages by default; I can’t think of one that gives me a mobile version by default. Bandwidth plans in Canada are pretty pricey so it can be quite annoying to watch MB burn as you load some homepages.
So to do my part I installed WordPress Mobile Edition and now the site has a nice little low bandwidth version for mobile access. Without changing the url.
