iphone invalid email/password...

I tried this and I don't know if it worked but I could log in after I did it: I went to Settings menu, then to Facebook app just to see if I had to tweek something, but the only thing appearing there was to allow Tags or not allow them in pictures... I moved the bar to on and off and then to on again... I went to the application and tryied to log in and it logged me in... I do not think it was what I did, since it had nothing to do with logging in, but I guess it's worth the try.

I am having problems with my first generation iPhone logging into Facebook, Twitter, Gmail... and I suppose other accounts... I called Apple, and they could not fix the problem over the phone. I am able to get internet and check my POP accounts... iPhone worked fine before I updated it... This could be the root of the problem. I reset it, re-installed the OS firmware.. etc... no luck. My iPhone is compromised...

Seeing it too. Can log in via web on phone, but not with application. If I put in the wrong password, it errors immediately. But correct pass hangs and never logs on..........

Same here - exact same as gb above. Can log on through browser, but not through app. Sucks.

same thing hear. tried reinstall and reset of iphone. removed numerics from password. nothing helps..

same thing with me too. It starts pissing me off. Exactly the same problem with you, guys...

do you guys have a jailbroken image? if so, the permission on /var/Keyrings might be your issue. ssh into the phone and run (as root):

chmod 777 /var/Kingrings

It should then look like this:

# ls -lad /var/Keychains/
drwxrwxrwx 2 root admin 136 Oct 3 08:53 /var/Keychains//

please let me know if this works.

err sorry i meant:

chmod 777 /var/Keyrings

Keyrings..not kingrings.. i need more sleep.

Yes, I am having the same problem. It's not your phone though, it's the account. I can log into my account fine on my phone but my fiancee's account DOES NOT work on my phone. My account works on her phone but her's does not.

Long story short, her account does not login on either phone. My account logs in on both. My password is non-numerical and so is hers.

I have this problem too. Just like Ryanschmidt says. I can log into my facebook account from my iphone or my wife's iphone but cannot log into her account from either my iphone or hers.

I am having the same problem. I can log in on the web but not through my iphone. I have tried logging on with other peoples' accounts and none of them will log in. Has anyone resolved this?

Today this just magically started working for me. There have been no updates to the App itself. I didn't do ANYTHING to my phone..though I spent 2 hours last night reading all about hacking, unlocking and jailbreaking, just so that I MIGHT try the ssh/chmod fix mentioned here...but I chickened out on ALL that hacking stuff....I don't want to BRICK my brand new 3G.

Earlier I had removed the numbers from my pswd, reset my device several times, reinstalled the app several times. Nothing worked.

Today on the way home from church it just miraculously starting working ;-)

Perhaps my iPhone sensed the THREAT of being hacked and decided to co-operate :-)

Or more likely, they fixed something on the server-side at FB that resolves this?

Hope that some of you will get the email notification from my post and try it yourself. Let us all know what kind of success you have?

Hello everyone... The same thing happened to me... I tried to log in about 1000 times every day and one time it finally worked!!! I now can use the application effortlestly and I have logged out and logged in again succesfully without any problem... I don't know if something changed at FB or if it was just insisting until it gave up... Anyways keep trying and maybe you'll be logged in soon..

Incredible! the same thing happened to me. For the last couple of weeks I have been trying to log in like a maniac and nothing. then this morning after I read the post I tried and much to my surprise was able to log in as well.

After all that effort the facebook ap is sort of a let down... but oh well! Thanks for the heads up!

I had the same problem, until a few days ago, when the error message changed to "can't contact Facebook" (or something alike), and a day or two later, it started working as it should !

Hey, I had the same problem, "incorrect email/password combination" on my G3. Googled the problem, this site came up, followed the advice of iPhoneNB above and it worked! Try it.
Thanks, BA

i'm mad
