Not exactly sure what you're asking but I'll tell you that I also got a GN2 after having an iPhone for several years. I immediately missed the visual voicemail and found a great alternative in an app called YouMail. Lot's of great features, not the least of which is you can blacklist people! Sales/Bill collector calls? Phone never rings, goes right to voicemail where they get their own special message "doo doo dooot...the number you have reached is not in service..." Brilliant!
voicemail can be transcribed and sent as a text message if you like. KILLER APP! (I'm reviving that phrase)
