I've seen lots of complaints on the fix (break) of Location Services in 2.1. Frankly at a minimum I think they need to put it back the way it was: if Location Services is off, you get a dialog giving you a chance to turn it on, instead of the lame new Micro$oft-type dialog we get now. Better yet, in Settings, give an option to turn on Location Services if an application needs it, and then turn it back off when you exit the app. I would expect the OS to be aware when an application exits, either to another app or to the home screen. Any developers out there that can confirm this?
