GPS devices may stop working on April 6

Since most of us will use GPS a lot, this might be of interest:

The week number in the GPS spec is 10 bit and will roll over on April 6th. This is like a Y2K bug, if the GPS device thinks week 0 is August 1999, it may not be able to determine its location.
No idea if this is a widespread problem, and even less of an idea how to check my devices. Devices built after 2010 should be built to the ICD-200/IS-GPS-200 spec and should be fine.
