Today I powered up my gps the first time and got a fix after 80 seconds. 
I was on a hill in a small village outside in a garden under a apple 
tree and the Freerunner was standing upright. Then I rebooted it and got 
an other fix in 80 seconds again. I've been using agps-gui. Much better 
than I expected. The Freerunner did see 5 satellites the first time, 3 
the second time.
