I have been playing around with my droid 2 since the update from Froyo to Gingerbread came out. Many features are now working properly, like exchange emails and imap emails do not show twice and do not trigger an endless loop of notification sounds, but the most noticeable change is the longevity of battery charge.
I have an exchange account and 3 imap accounts, and a gmail account. With Froyo, enabling push emails made the battery run out in 3 hours. I had to keep my phone charging at my desk and in my car.
After upgrading to Gingerbread, I have gone 12hrs without charging. I only charge my phone during the night, and during the day I do not worry about charging it.
Received the new Market update and I am now able to download Netflix on my Droid2 Froyo Verizon 2.3.20.A955.Verizon.en.US
I am able to look through my instant queue and have watched Futurama, National Geographic documentaries, and Blade 2. I assume all the other movies are playable.
Interestly, I did not have to add/activate a device to my netflix account. I was one of the few for which Netlfix was not available since its May 13 release. Now I can vouche it is working. I believe some of you with Droid 2 Global and Droid X had similar dificulties, hope this update works for you too.
