Just came here to ask about the 710 actually, as it has started crashing on me today. I uninstalled and reinstalled it, but it randomly closes down. It is one of my most used apps as well, so hope a solution can be found.
Same here - it seems to be something to do with location services. I tried pressing 'Cancel' rather than 'Accept' when the app asked if it could use my location and then it worked fine.
