Q. I'm pretty sure that Assisted GPS is set up properly, and yet my Nokia still sometimes takes up to ten minutes to get a GPS satellite lock. Is it faulty?
A. Probably not. Establishing communications with umpteen satellites whizzing around the earth is actually quite hard, you know. And you need line of sight for each, so try to get a lock in the open air, away from buildings. Time to first lock is also dependent on weather (clouds get in the way, degrading and confusing the signals) and how long ago it was (or how far away you were) when you last had a lock.
In rural areas, with blue skies and having only used the GPS module a few hours ago, it's possible to get a satellite lock in Ovi Maps in under five seconds. At the other end of the scale, trying to get a lock on a cloudy day in the city after having not used the GPS for a couple of weeks will take, yes, ten minutes or more.
Be sympathetic to the hard job your Nokia's GPS is doing and I think you'll find the short wait more bearable!
