Weather tab...............?

[thankobidient]

Yesterday i got a replacement phone from U.S.Cellular coz i had trouble connecting to the internet on my original Touch Pro 2.

But now i am facing another problem. The weather tab is not working, means its not automatically picking my location. Whenever i hit the update now button. its shows " updating weather data" but after couple seconds it shows " no weather update available".

My gps is working fine, but don't know whats wrong with the weather tab.
When i talk to the customer care center they told me that its not their prob and i should call htc regarding this.

Wondering if anybody can help me out?
