Yup. This and the (somewhat) flimsy keypad were the biggest disappoints with this particular model. The only reason that I ordered my M2 card was to have the option of using the phone as a portable music player. It arrived before my phone did so I was disappointed after I opened the actual box to find no adapter. It really *should* have been standard - especially with the Walkman brand on it. :(

Actually I was hoping that someone would attempt a mod to add one.
