Does anyone know how to reset/clear/delete/restore the google maps cache? I'm not sure if my maps app is corrupt. If I start to zoom in or move the map around quickly and cause a 'lot' of data to be downloaded at a time, it will go into a sort of freeze mode where the gray squares will not go away and the spinning wheel in the status bar doesn't stop. When this happens, I've tried leaving it alone for 5-10 minutes and upon turning it back on, the gray squares are still there. If I move it around very slowly, then all of this is less likely to occur, but will eventually occur. If I quit the mail app, reopen it, the gray squares are gone and that area of the map I had been looking at previously has been downloaded successfully. I've tried restarting multiple times to no avail. It just started 2-3 days ago around the time I updated Angry Birds. I don't even update apps that frequently, so nothing else to blame, really.
