Was wondering if anyone else had seen this.
The wife and I were having the same issue, but for some reason only after the 2.2 update. I had just switched from the old Nite Eyes velcro-closure pouch (used w/old MotoQ9c) to the Verizon magnet closure acquired w/Droid, but she has been using that one all along; I had to take my phone and hold it next to the flap and then the body of the pouch to prove to her that that was doing it. (IIRC, the flap magnet activates dock mode, the body magnet activates car mode.)
