I can't post mobile pic's at all. It drives me crazy because once in a while it might work. At this point I would actually pay for a FB app that worked.
For me ever since the push came the this app is when I started to have issues.
I even deleted it from my phone and iTunes and re-installed it and nothing.
Is there a setting in Facebook itself that can prevent me from uploading pics from my iPhone?
EDIT: I found iLoader and got the free version and so far it's cool. You can upload multiple pictures at once also.
