I missed completely this, but Wikipedia officially launched a mobile version, at http://mobile.wikipedia.org/
For me this is a great news, as the “standard” Wikipedia interface is difficult to handle on a mobile device, even with a good browser as SkyFire is (non-us residents read this). And I often look for info on Wikipedia, both english an italian versions, on my mobile device.
Tried it, and it’s good: fast and well-organized, all internal links point to “mobilized” versions of the pages, I like this.
