I just d/l and installed it, it's set to observe gmail changes, I confirmed the service is running and have sent myself a test message but it won't show any of my gmail in TS, it says "No events"
I then added the TS widget to my homescreen and tried to see if that made a difference, nope. Damn, got me all juiced about this
I wonder if the absurdly long sync time even with the gmail app itself has anything to do with this. I'm on wifi, just opened my gmail app and it's been on the "waiting for sync, your email will appear shortly" screen for a good 5 minutes. So I turned wifi off, enabled 3g data and i'm going on 2 minutes sitting on that screen......horrible!
