Yes, i'm hearing that this does not work, for several other people here.With all due respect, it is not working for me.
I have tried to email pics to "10digitcellnumberhere"@mms.att.net to both cingular/ATT customers and to verizon customers who all have mms capablity and plans.
(these 4 or 5 people and I have sent pix messages back and forth for a couple of years now)
Either the text only goes through or nothng at all goes through.
If I email a pic from my iPhone to a normal email address like "firstname.lastname@example.org" the message and picture go through fine.
