My Facebook for iPhone app is unable to login?

[heatherliak]

I have an iPhone 4, and i had the newest version of the Facebook app. I recently downgraded to the one before the newest because I figured the bug would go away. Whenever i try to log in, it says "Login Failed, please try again later" It has been like this for a couple days. I have tried logging in with Wifi and using Verizion's 3G. Other people can use my phone and their accounts and it works fine. Its just with my account. How can i fix this?

I am facing the exact problem, tried searching at number of blogs and forums, but no concreate answer.

I am using safari browswer to log in to facebook, the UI sucks but no other alternative. FACEBOOK really needs to look into this.

Same problem here. Gone 4 days now. Have uninstalled and reinstalled the app. Have changed my password and security settings. Still no go. I am able to login via Safari browser on iPhone and desktops.

I FIXED IT! I FIXED IT!
Log onto FaceBook on your computer. In the upper right hand corner select Account, then Account Settings. Now select your email & click on “Add another email” After you add another outside email account, select it as your primary account. Delete & reload the app to your phone & use the new primary account. IT WORKED!!!! Good luck…
