The upgrade went smoothly, but I have two side effects:

a) Boingo fires up and logs on every time I connect to any AP.
b) (may be coincidental) I haven't been able to get a GPS fix even once since the upgrade. Rebooting doesn't help, agps-ui says the cached data is valid. Maemo mapper currently (30' after startup) shows 9 bars with strength values in the 27-34 range (which do change, ie the gps driver isn't stuck) but no fix.
