Are you on IDEN or CDMA? I"m guessing CDMA based on your phone list. I've been using GV with an IDEN 8350i on Boost for about 6 months now. But planning on switching over to CDMA soon. IDEN would send calls to Boost voicemail before GV would and there's no way of extending the ring time. You have to set up conditional call forwarding on your handset to use GV voicemail. Does CDMA ring long enough to use GV voicemail? What happens when your phone is off or out of service? Another feature unique to Boost is you aren't charged for Instant Messaging on Nextel or Sprint phones. I use GVMax to forward my texts to Google Talk so I get unlimited texts free. With pay-go Boost, I'm only paying about 15-20 bucks a month for service. Unlimted texts, web, and just paying per min on phone calls. I use GV+VOIP for free calls at my house so I just use minutes when I'm at work or out.
