I just updated my Epic 4G to Froyo 2.2.1, and I just realized something--remember that one option you got when you repeatedly failed to input your unlock pattern--the one where you could unlock with your Google account? Well, apparently with a PIN or password unlock, that feature is absent. Any insight? I'm just worried about what to do when I suddenly forget my PIN and can't unlock the handset. (Ruling out the option of flashing my phone, hard resetting, etc.)
