iPhone experiencing GPS problems after 2.0.1 update?

While some complaints after any firmware update are to be expected, there seems to be a decided uptick in the number of reports of problems with the iPhone’s GPS (ranging from general wonkiness to all out failure) after the most recent 2.0.1 update. As the responses on the MacRumors forums indicate, however, the problems are far from across the board (or confined to the iPhone 3G), and GPS problems haven’t exactly been that rare of an occurrence before this latest update either. So, we’ll open it up to you, dear readers — have you had any newfound iPhone GPS problems?
