Hi!
During the last week I have been seeing strange activities of my iPhone (2.2.1) GPS receiver. When using Maps, it first triangulates my position using cell sites and shows blue circle, after a minute (sometimes quicker) it locks GPS signal and blue dot appears. Up to here everything seems normal, as used to be before.
But then after a few seconds bluish round appears about the blue dot (indicating worse accuracy of the GPS coordinates), a few seconds later bluish round increases, after another moment blue dot disappears and triangulation circle pops back up. After that, sometimes sooner, sometimes later, sometimes never until I restart Maps, the blue dot comes back and disappears again, and so on... All of this takes place outdoors, no tall buildings around.
A few days ago I met my friend who also owns iPhone 3G and we have tried to check the GPS together. I was surprised that the GPS coordinates were locked and lost almost simultaneously on both devises.
Has anybody of you seen this? What could be the reason for this malfunction? Could it be that some GPS satellite is down, or iPhone GPS receiver is broken? I would not guess that it is weather conditions because it lasts for about a week, and I am sure I got GPS working correctly before even in more cloudy conditions than this week.
By the way, I am located in Vilnius, Lithuania. I am looking forward to your thoughts and ideas! Thanks!
