Any suggestions on making this more instant? I really want to ditch my SMS plan, but the GV notification is spotty at best. I thought SMS was push now? As in, you get an SMS/VM/ETC, Google Pushes a notice to your phone to sync, then your phone syncs? It seems like it's still just checking every 10 minutes or whatever. I also have the extension in Chrome that shows your SMSs, and the two don't correctly correspond on new messages. Anyone use GV as their sole SMS?
