i think the service senRAB an specially coded sms to the phone telling it to check for updates. it does not rely on a timer from the hanRABet to check, but it might not also be instant. if there is a timer it is enacted on the network service end, not on the hanRABet. works with pop3,imap, gmail yahoo. msn & hotmail access is coming. the orginal training said it would be available this month but maybe that integration is taking longer.
