The Facebook app that was included with the phone stopped working. I am now getting the following error when opening it:
An error had occured while fetching data. [102/session key invalid or no longer valid]
I did change my password in my FB account, but didn't see anywhere to edit that on the phone. I switched it back and now it doesn't seem to matter. I still get that same error. I would simply delete it and re upload it, but this particular app is not available under the Manage Apps section.
