unlocked + aGPS might be bad combo...

[BigDiesel07]

A great point has been made here about a possibly bad side-affect of having aGPS turned on.. As quoted from the article...

If you're using an unlocked device or an otherwise non-carrier-supported device, it's a good bet that turning on aGPS is going to lengthen your acquisition time as the assisted part of it tries (and fails) to get location information from the local tower.

So if you have an unlocked phone, it might be a good idea to turn aGPS off.. I believe a registry edit will do the trick.. For an expanded read of this possible problem, go here...
