How to get the longitude and latitude from the GPS on WP7?

I'm writing an app that needs to get 开发者_C百科the longitude and latitude from the GPS on the phone. I'm saving up money to buy a phone, but for now, I'll have to stick to the emulator. Is there a way I can simulate some fake, random gps settings with the emulator?

A question aside: Is there any Windows Phones I should avoid buying, any tips?

The emulator on its own doesn't provide any "fake GPS" support, but there are a few emulator tricks around to allow you to fake GPS data:

e.g.

• http://phone7.wordpress.com/2010/08/19/gps-sim-update-generic-model-and-dll/ - see http://phone7.wordpress.com/2010/08/02/no-device-no-gps-no-matter-with-code/ for pictures
• http://wp7gps.codeplex.com/
• the official one is http://windowsteamblog.com/windows_phone/b/wpdev/archive/2011/01/28/windows-phone-gps-emulator.aspx

I've previously used http://wp7gps.codeplex.com/ solution - I chose it before the official one was out as it gives you the same data each time (helped with testing)
