I found a few places that discuss how to add mp3's to your voice mail greetings. I am curious, is this going to cause issues? info says to use OpenSSH from Cydia - and then to convert the .mp3 to an .amr file then you use cyber duck to transfer the file. I understand the process, but is this hacking or jail breaking my phone? I don't want to have issues on my brand new 4S All I want to do is to add a cute little voice mail greeting instead of the AT&T Default or custom voice.
