Well,

   Sean is sick in bed from taking Malaria shots since he is traveling to
Ghana to speak. I have been
   Busy at the wharehouse and Wolfgang is aware of your issue and we have
folks on it trying to duplicate
   the issue and figure it out. Sean, for example, has had no issues in TPE,
west coast USA, east coast USA,
   and columbia with his phone.  So, after we duplicate the problem then we
can figure the cause. Software,
   component failure, test leakage.

   On the inside of your phone there is a datecode, serial number etc.
Email that to wolfgang

Steve

It seems nobody gets a quick fix. Times range from 10 to 60 minutes if any
fix at all. There is a similar thread running on the developer list but no
answers from Openmoko. Normal for a cold start would be 45secs-2min and with
agps ~15secs. This is industry standard and stated on the specs page of
u-blox. The GTA01 (Neo 1973) gets a fix in one minute after a cold start.

All modern chips (and the u-blox is a modern chip) can get a fix without
downloading the full almanac (which takes 12.5 minutes). The ephemeris is
sufficient and comes in 30secs.

I think this is an important issue and hope that Sean or Wolfgang can give
answers. I CC'd Steve too, because this equally effects the VAR markets.

If they don't answer it is probably the best to send your FR back before the
warrenty expires and buy a new FR once this issue is resolved.

Marcus
