I've never had an issue with the volume on my phone either. I can hear it from across the house...at times it might be too loud actually. I also haven't had any issues with Visual Voicemail. The volume quality there has been pretty clear. I'm not sure about nesting folders with in folders as I haven't used folders really. I have put my most highly used apps in circle launcher and cleaned up my home screen a good bit to make more room for widgets.
