facebook was down for me for the last hour, couldnt fatham out what was causing it, so tried on my desktop and when trying to login it said my account was down for general maintanance and that i should be able to log back in soon, needless to say, im back in on my iphone now,

shame it wouldnt tell me that when i was trying to login instead of just returning me to the login screen again.
