iPhone Weather app can't display below zero

It appears that the Weather application on the iPhone (powered by Yahoo! Weather) can't display temperatures below zero degrees fahrenheit. As reported by one user on the Apple Discussions board:

"I live in Alaska. The temps here have all been below zero F or more than -18C but the weather reported on the iphone never goes below zero F. right now it is -13F and going to Yahoo says this but the iphone shows 0F. "

While the Weather application will display temperatures lower than zero degress fahrenheit in the extended forecast and the high/low temperature for the day, the current temperature reading cannot step below this threshold. Yahoo's Web-accessible weather data will show temperature data below zero degrees, so this appears to be an easily fixable bug in the iPhone app.
