Up and running with the Froyo now! After it installs, it restarts. Mine hung for about 5-10 minutes on the Verizon animation before it finally loaded the screens. It does reset all the home screens to default, so I'm in the process of reorganizing everything how I like it again. Browser speed is definitely faster. Haven't tried flash yet. GPS locked on the fastest it ever has on this phone.
So far so good.
