Hey all, First post here, I hope to frequent this place more often! I have a question regarding voicemail on my Thunderbolt; I have an mp3 file that I would like to set as my voicemail greeting, but I am having a hard time figuring out where to put the file. Furthermore, I don't seem to be able to find any saved voicemails on the phone at all. Anyone have some insight? Thanks in advance!
