Ah, my favorite topic, I think I'm in love with mobile operators.
Ok, it looks like your mobile phone is locked for socket connections. Just to be sure download Opera Mini and try to play with "HTTP connection” vs “Socket connection" settings. It's described in their FAQ http://www.opera.com/mobile/help/faq/ in "What is the difference between “HTTP connection” and “Socket connection”?"
Bloove Agent works only via Socket Connection right now.
