i have a 3g on 3.0. on att.. set it up for mms but i dont have a data account.. i tried to send a multiple sms message today and it failed. after i reset the network settings it worked fine. another question. when mms does come out for att is there a way that att can only allow data for mms and not internet or youtube? i have all internet turned off on my account. 3 iphones... but i really want mms to work. or is there a setting in the iphone that i can use to eliminate it using 3g or edge for safari or anything else other than mms?
