Is it possible finallyto attach photos to text messages through MMS on the iphone 3Gs? According to David Pogue (iphone:the Missing Manual, p. 84), there should be a camera icon next to the box where you send your text messages. I do not find this icon present. Also, in the photo app, I do not find an MMS box like the E-mail box that I can click on to attach a photo. Is this feature not operative as yet, or am I missing something
