at OP: If it really looks official, just take time to confirm you are not the only person receiving this treatment before you send your current device back to "Nokia".

Maybe you'll find the roadmap for the next 2 decades, source code of Maemo 5/6, including drivers.

Maybe it used to be Elop's and has a low profile built in broadcasting HW uplink to MS Headquarters for use during MeeGo progress meetings.
