Hi,
The mobile site is great. A few small suggestions:
1. An 'x' in the search box would be great to delete old searches
quickly, as in eg Google mobile
2. If possible, disable iPods intrinsic word predictor/spell checker
as most words one types into wikipedia are not very common and
therefore do not come up in the predictor anyway
3. If possible, incorporate wikipedias own predictor in the search box
as this is vry useful!
Hope that's helpful!
