I use an app called Night Stand (something close to that) and it uses Wifi to update the weather in the app, but after i updated to 4.0, every few minutes after the app is open and idle, it pops up saying it is unable to determine my location. I was thinking that 4.0's "smart" wifi may have something to do with this. My location services are ON and enabled for that specific app. This didn't happen with 3.1.3. Any ideas?
