>>when i click the "download now" button i get an error saying the conten cannot be downloaded. error 406
As was stated above - this is probably a MIME configuration issue (i.e. the server yr using ios not configured to allow mp3. Can u download the mp3 via your desktop browser?
Important fact concerning the 8700 and the 7130 : depending on the carrier, the device may or may not allow access to different audio codecs. The 7130 supports mp3 but some carrier (ok - one i know of) has disabled this in the firmware. One version of the 8700 that i know of actually supports mpeg audio (mp3), AMR, ADPCM, and WAV
