I've tested the solution above and while it works for a success page redirection it doesn't work for allowing the likes of Facebook, Youtube or twitter apps on iOS devices. Looks like i'll have to wait for an apple "update" to hopefully do something that fixes this.
Cheers for the help guys
TQ
This solution is not intended to fix your Facebook problem. It is workaround for Apple's "CP improvements" as described on many other forums as well as here before. Maybe I hijacked your thread with this, sorry. I don't use/own Apple products, so I cannot test anything, but if you do some packet capture and post it here maybe we can come up with some solution.
