Hi Docent - your post might actually be related to mine, in a strange way. I hope Sergey is reading this as well - because Houston: We've got a problem!! Here's what happened to me:

The other day I got information from my company, that I should sync my N9 against another MfE server. So replaced the existing server with a new - and the phone synced. At least I think it did, because I watched it start, and put the phone away.

When I picked it up again, it was locked... Firmly! I did NOT set any code - I was not asked - and still... locked! It said "Angiv Låsekode", which translates into "Enter Security Code".

The phone could receive calls, and dial emergency numbers. I could enter pin-codes as much as I wanted - from 1 digit up to 30 digits I think. Tried about a 100 times. I could not enter letters, I could not leave it blank, I could not long-press and nothing I did had any effect. It did not lock itself further or threathen to erase either.

Tried all pin-codes I've got (which is 1 - not much to be mistaken about), tried the track&protect pin - but nothing worked. Entering my MfE-code was not possible, since that consists of letters and digits.

There are NO policy settings on the server, according to the MfE experts in my company.

My conclusion is that the N9 can lock itself upon a change in MfE server.

I had to send it for repair here in Denmark - and the repair later sent it on to Nokia's HQ in Finland for furhter testing. I do not expect to see it again, since it's probably worth having for the developers to experiment with.

So, Sergey - If you want to find out more about this problem - your colleagues have got an example - sent with greetings from Denmark.

This is the thread I've been posting in - and it contains links to several other people in other threads that have had the same issue. http://talk.maemo.org/showthread.php?t=80821

Thanks to Jalyst for pointing out the relevancy in this thread.
