Why is the weather forecast of htc hd2 always in Taipei?

I have only used HTC Android, but I think it can be solved in the following ways.

1. Turn on the GPS of your mobile phone and locate your position.

2. Turn on the GPS and modify your position through the feeling of desktop weather forecast.

Because HTC is a brand in Taiwan Province province, the initial position shows Taiwan Province province. Maybe you bought a desktop version of HD2. I hope the answer will help you.
