So I think I learned something about Gmail on my Incredible -- don't set the "Number of days to sync" to 100! I did that and the DINC's storage filled up and the device really slowed down. Even after I went back down to 10 days the little 'refresh' icon on the taskbar isn't going away. I suspect it's going to take some time for it to play catch-up. I have a couple of dozen Gmail labels and I'm not sure what made me think they ALL had to sync back 100 days. Doh.
