I have a factory unlocked 3gs 8gb from Canada running t-mobile. I have the 4.2 update. I can't get picture messages from anyone. I can send one and send one to my phone. I just can't get one from anyone else. I have read all of the t-mobile forums and spoke to t-mobile, but can't seem to get the right answer. I don't want to download anything from cydia. Does anyone have the right solution? Thanks
