BerryWeather, but it's a pay application. Sultan, the BerryWeather application rocks, Rachel and I just purchased and downloaded it today. Very nice indeed...
Berryweather - I bought it. But it says "update failed" each time I try to update current location. So far nothing fixes this. Tried all configurations, re-installed it and ensured it was the current version.
You might want to do the trial first in case it doesn't work for you, either. I'm on Sprint.
