In this video i show you how to enable mms for your iPhone, mine is unlocked with T-mobile and this is the process you need to take to send and receive picture messages. All you need to do is go to your Settings. Then go to your Cellular Settings and fill out the settings that are shown in the video!
I understand that you have to use email to send pictures with the iphone but lets say that i want to send a picture to my girlfriend who has a blackberry pearl without an interent plan. Will she be able to get the picture and download it just using media net? And would she be able to send me one without having the internet plan? She has the new pearl but does not have the interent plan for it but does have media net capabilities.
