I'm in the san francisco bay area, and am seeing very slow GPS fixes. 
It took 5 minutes to get the time code from the satellite this morning 
(didn't get a fix in 12 minutes...), and I've only gotten a fix once so 
far (after > 10 minutes...), and it's failed to get a fix during a few 
~10 minutes walks outdoors.  I've been carrying the phone screen up, 
away from my body, away from buildings taller than a story or two...

Anyway, if you still haven't duplicated the problem, let me know.

Also, I'm getting a bit of GSM data noise on my speaker during phone 
calls.  Is that normal, or is it unexpected signal leakage?  I plan to 
retest GPS with the GSM (and all other radios) disabled.
