I'm not sure if it's AT&T or if it's my phone (a Samsung Solstice), but the emails I'm getting don't have any songs attached to them. On my 4-year-old $20 Verizon prepaid phone, the entire process worked perfectly. On this expensive, bells-and-whistles one, it won't. All I get is a text message with my email as a link, and the subject of the email (if there was one) in parenthesis. No music, nothing else on the screen.
And please don't suggest that I read the help sticky. This isn't my first time on a forum; I've checked there already. I sent emails using both addresses for AT&T, and I get the same result.
