How could the GPS work in flight mode (which should mean the CDMA radio is off so it can't tell if I am in a CDMA area or not), but only if I'm in an area with CDMA coverage? Since GPS is sat dependent and the phone can do that with all radios off it should work anywhere I can pick up a sat...

Unless I understand the technology or flight mode wrong?
Several of us have tried to get a lock out of the country. I have tried it in Europe. While (using a diagnostic app) it will briefly see sats, it fails for some unknown reason to establish a lock.

My personal belief (with no evidence to support it one way or another) is that the driver is optimized to lock quickly. As such it is limiting the allowable band of coordinates to North America to reduce the search area when doing a cold start. To double check your locking in flight mode, I suggest trying the following. Put the phone into flight mode, then do a full power down (hold the power button 5 seconds). Then turn it back on, and without enabling the radio, try to get a lock. Ideally, you'd leave it off all night to completely ensure the GPS state is cold as it may store it's last start sufficiently to recover.
