I'm new here, my wife uses an iPad2. Also have a Facebook problem. Sounds similier. She starts Facebook. Gets a white srceen, immediately followed by a blue screen with Facebook written across the center. It then disappears, going back to the normal apps screen. If you go check the running apps, it shows Facebook running. Still running IOS5, updated Facebook the other night to ver. 47423. Have not deleted Facebook app and reloaded. I guess that would be the next thing but am not sure what gets deleted when apps are deleted. When you go to delete the app, it says has a warning that data will be lost. Is any important facebook data actually lost or is the warning talking about the app only? When Facebook was initially updated it didn't work for several housr, then started working. Worked for several days and now has not worked for 2 days. Sorry about the length, I was trying to get all the info in. I guess the question is; is deleting the app any big deal, unless somebody has the actual cause of this problem.
