This is an actual screenshot of an attempt to get a weather report for Tartu, Estonia on my iPhone, using the standard Weather app, powered by Yahoo data.
What’s the joke?
Yes, the city of Tartu used to be called Yuryev at some point. Namely between 1030 and 1061 when Prince of Kiev, Yaroslav I the Wise burnt down the wooden fortification dating back to 7th century and built his own.
Just checked, Yahoo! Weather on the web has the up-to-date name. So apparently it takes a tunnel through Apple to get medieval.
