Connecting facebook and wordpress

I finally got around to connect my blog to my facebook account and run into trouble enabling a developer account. To use the wordpress facebook plugin you need to create a facebook app that can post to your facebook account.  To create the app you need a facebook developer account. So far so simple. The tricky part is, that you need to link your facebook account to a mobile phone. In my case the confirmation code was simply wrong and I could not get it to work. Different solutions are reported here:

In my case replying with “F” to the number that send me the wrong code performed some magic to send me a new (correct) code. The SMS with the correct code was in German while the SMS with the wrong code were in English.

So I assume facebook has some problems when people do not use facebook with their native language).
