I looked around for some last night actually. old devices, so I could grab a few for testing.
Near as I could make out everything before a 3 was either "dead" or "not for sale".
Or for sale at a ridiculous collectors price. (err really? a device about to die?)
So my thought would be that the K2 index will slowly die soon as the devices do, that is a very sad thing to say but the battery life of the device is sadly outstripped by people length of love for them.
Hope you get it sorted in the interim.
(I look at my k3 and see it's sad one-day destiny written in this post)
