Thanks Juan. I tested at home adsl without any proxies or firewall. Also, I tried at university. I don't know about firewall or proxy but Iphone can connect with university network to moodle mobile now. In fact galaxy note 3 could connect with 3g but rejected wifi connection before the last update of moodle mobile. But now it also rejects 3g connection.
