Thats not quite what he asked for... Who are you to play the moral police?... You're basically saying he can't use iChat, iCal, etc. It's HIS computer and he should be allowed to use the software he PAID for. Does it mean China is doing right by banning half the internet? It's THEIR country and they have the ban for a reason? Thats complete ludicrous, what ever happened to freedom of information?
To the OP, I'll post if I find a solution, atm I'm running FreeGate via BootCamp because my school's wifi has certain legal sites etc blocked as well.
