Ericsson made some interesting accessories for the T28, like the "CHA-10 Chatboard" (a QWERTY keyboard for text messaging), the "MP3 hands-free kit HPM-10" (an MP3 player with an MMCcard slot and standard 3.5mm headphone jack) and the aforementioned "Bluetooth phone adapter DBA-10".
In addition, its card reader supports SD card and MMC, so customers can play their music and video directly from the card, or upload photos, video and music to their favorite sites.
