Droid X: What are the pros/cons of upgrading to Gingerbread 2.3?
I can only speak from personal experience.  I have updated my Droid X and since then I have had many issues with it.


It seems to be unable to send texts or make calls that require a battery pull to fix.  I have to pull the battery at least once a day.
It will not find the GPS, it is constantly searches for GPS.
Any videos I had played previously through the gallery will freeze if I try to skip.  I got the Mobo player and must use Softdecoding in order to play movies where I can ski .


Some positives


I like the darker look of the OS.
The quick text when you are ignoring a call is very nice
It seemed a little faster


Personally I wish I never upgraded.  I am really close to going back to 2.2, but I do not want to go through all the work involved with downgrading.
