Would you take the risk? I wouldn't.

Especially given the previous Nokia track record (supl.nokia.com not working on N900's since forever, maemo.nokia.com shut down more than 1.5year ago, ovi files shut down with a month's notice, autobuilder/wiki down for months etc.)

BTW the reason it was running mid-January was that the migration was underway, and they accepted to keep it running until the move. The tmo invoice was expiring 20/01/2013 and we moved out on the 16th.
