Comment(by thomasg):

 I can confirm this.

 I'm a lazy person, so I just copy my mail:

 I also did some testing with all the pieces of hardware the freerunner
 has.
 The GPS is very disappointing. I could get a fix in about 2 minutes with
 my
 Neo1973 with a cold start.
 This works inside my car (maybe a bit slower), at my room's window (bit
 slower), and everywhere outside.

 I still didn't manage to get a FIX with my Freerunner. I tried it at my
 window (nothing at all), in my car (nothing at all), outside my window
 (first coordinates after 15 minutes, no FIX at all), and on top of a hill
 with sunshine and no clouds (first coordinates after 5 minutes, no FIX at
 all).

 After that tests I don't think that my Neo will be able to get a FIX ever.
 At least it's totally unusable as any kind of GPS- or Navigation-device.
 Getting coordinates from my CellID-database is barely less accurate, but
 it
 goes in no time and everywhere.

 Btw. - I took a picture of my GPS_antenna, and I just can't imagine, that
 this will be able to get a GPS signal without siginficant loss to the
 reciever (that has only a sensitivity of -155 dBm in the best case).
