from post #2:
" A new "Jumbo" version of the #11 has just been released. It is functionally identical to the v3 with identical CMOS/Lens module and video processor IC, but has a different circuit board layout and a larger battery, good for about 100 min. recording times. It uses the same firmware and comes in three slightly different case configurations with several different trim schemes as well. Case sizes are 65x35x18mm or 70x34x18mm depending on what style you picked (compare to the original 51x32x14mm case). All of these will be referred to generically as the "Jumbo #11" in this thread and will be given no other special coverage."
Both have a power button and a shutter button.! Neither has a "lock" or "unlock" button. If you had just reflected on this and noted what the small button of the small version does, it all makes sense, or should.
