There isn't anything changed to the GPS you know? Nokia did not upgrade the GPS chip via OTA update lol. The hardware is fixed and cannot be changed but software enhancing it can be changed and in this case the software is the same as previous PR1.2 so I don't see why you keep saying that you have faster locks.

Sometimes is due to whether, clouds, satellites positioning in space, someday there are 3 or more satellites positioning is at the right location to communicate with the GPS chip. Sometimes because you using the Data connection and helps the positioning better than offline cold start.

Just remember this, once you got a lock, the next time you wanting to get another lock is easier and faster than previously. In this case it is nothing more but a Placebo effect.

It happenes all the time, it is all in your head , sometimes your eyes lied to you more than your friend did or your gf did. Sometimes when you desparately hoping for something better and your brain fooled your tought.

Example: A soldier who get shot will not be able to feel the pain and will not know that he got shot. Not until he sees the blood and then he starts thinking about it, that's when the pain is trigger

Simple comparision
