If you are having trouble logging into Facebook from your iPhone you should first check the login information through the web browser, which you can try either through Safari or on a computer.

The Facebook iPhone App has been designed to simply log in your information automatically once you have entered it, so that you do not have to actually enter your account information over and over again. If this information has been entered incorrectly it may cause trouble logging in automatically and you may just need to re-enter your account information so that automatic log in can continue.

Though most iPhone apps have their own app-specific settings in the iPhone Settings area, none of the settings for the social networking iPhone apps have anything that would give you trouble logging into them. If you believe that you are having trouble logging into social networking iPhone apps because of the lack of available Push Notifications then you should check the settings for each individual app as this is likely the source of the issue, and not a problem with logging in.

Find a friend with an iPhone or cell-phone and a computer.
Connect to FaceBook, and enter the friend's telephone-number,
and answer the telephone when Facebook calls.
