does the facebook app not work with 4.5? mine is not showing up and i also tried to install it again. when i go to applications its there but the home screen icon is no where to be found.
I just noticed it was gone as well. It's not hidden. I tried a couple of different themes and it's not there. It does show up in my Applications list though. (Ver 1.2.0 if it makes a difference.)
When I updated the last time to .69 on my device, Docs to go did not get installed by default. You might have the same thing going on and don't have that icon on your screen. You can install it easily by using the Desktop Manager -> Application loader. Look for the Docs to go checkbox and see if it's installed, if not, give it a shot!
