The specs for the 6230 say: "Integrated video player: 3GPP spec (H.263 video, MPEG-4, and AMR audio packed in .3gp format)"

I'm developing 3G media and would like to know if the video player supports playback of AAC-LC or AMR-WB encoded audio streams in the .3gp video file?

It would be a shame that with an AAC/MP3 player built into the phone, it is unable to playback AAC streams in .3gp files as generated by many authoring software.
