That's very interesting. After comparing your platform to my phones platform, it has to be a bug (a weird one at that). My platform is exactly the same as yours :P
Sure you may ask :P
The info I got is:
Suplier id: 150 (KPN from the netherlands)
Then you get the pin, IMEI and MAC.
I find it after pressing alt+sgift / arrow up + h.
I have no idea if its actually running on OS6 because I dont see any changes after an update.
The update was done by hooking it up to my laptop, it told me there were updates and I installed them.
Then it changed from 5.0.822 to this 6.0 version.
