We all waiting for the NoDo-Update – some sources announce the update around the 7th of February. But Microsoft looking forward and have now published a knowledge base article about troubleshooting problems during the update process of Windows Phone 7 (hope that there are not a lot of)
Troubleshooting problems during software update for Windows Phone 7
In your Windows Phone device you have a built-in Assisted GPS (aGPS), which can be used to access location informations by using the System.Device.Location namespace. The GeoCoordinateWatcher class supplies location data based on latitude and longitude coordinates. This is nice, but if you want to develop such an application it is necessary to emulate the GPS sensor.
In this Windows Phone Team Blog a very good article can be found to achieve this goal.
Eric Law on his MSDN blog has detailed a method using Fiddler to watch your phone's data traffic over WiFi (so this won't help with that 3G issue). Primarily this is a great tool for developers to make sure their app is not using excess data in any way but it can also be useful for those who just want to know what's going on.
My article in the german Dotnetpro magazine about data access with Windows Phone 7, I have written with my SDX colleage Matthias (see Mind-driven development), is now out: http://bit.ly/hzYWFC
