This is my first BB, moving over from a long line of Treo's, most recently a Treo 700P, may Palm rest in peace. So i get email attachments of voicemails from my work pbx and they are .mp3 files. Is there any way to listen to these on the BB 8130? When i click the attachment, it says unrecognizable file format. On the Treo, it just plays them.
