My turn-by-turn Sprint Navigation magically became Sprint Navigation Lite today. An "advanced" Sprint tech told me it's happening after the 2.2 upgrade, although I did that days ago & the nav was working just fine until today. She said all I can do is a hard reset (re-provision the phone). That scares me to death...not sure how to back up what to where. Is she correct?? The app runs as the Lite version but does NOT pop up the option to upgrade. Thought I could upgrade and then have them take it off the bill....but NO!!! Please help - any ideas or tips on backing up EVERYTHING would be greatly appreciated. Thanks!
