Dear Andrew;
I looked at the instructions as to how to get the crash log from the phone, but my version is old - 4.3.5. I can't find the Diagnostics & Usage window under General/About. I have avoided upgrading my OS because, in the past, I lost much of the information on the phone. According to Apple, my loss of information in the past is because I was syncing it using my Windows computer.
If I reinstall the app, how much data will I lose? All my saved tracks have been sent to myself, and I could always reload the maps. Or, I would sync my phone to my wife's Mac, but she (and it) are out of town until next week.
Thanks for your help.
Mike
