You know, I have tried several programs that convert mp3's into ringtones but 99% of them output terrible sound. Media Audio Cutter works the best, the sound is great. The program costs $15 and it takes a couple of days to get a registration code.
It can export as a MMF, which is what the Helio Hero uses. Export and use the Data Manager to sync. Done. I'm sure the program can work with muliple phones. Also exports in m4a, wav, mp3, mmf
The actual phone itself has everything but Bluetooth, so if that's a priority...move on.Media Audio Cutter Homepage
