Hello and thanks for the response ! A couple further questions :
1. I might have not configured my app right on facebook. What do I need to do to have it set up correctly (I'm currently developing so I havent sent anything to Apple for validation or stuff (as you can see it's my first time!)) ? Is there a particular setting I must use ?
2. I'm pretty sure I set up my app.xml correctly. I used the following lines in the CDATA of the <iPhone> tag :
(the 9's are my actual app ID)
3. I don't see the useNativeUI property. Maybe I'm missing something ? (All I see is the use native system flow or something like that, is this what you're talking about ?)
4. I've tried with and without the facebook app, but thats not what I want. I want to have the login window inside my app ! As I said, it works when it comes to publishing to wall. But not for the login.
Thanks so much for your time, I'll look some more into the things you've pointed out !
