As you know the VX4400 notifies you once for an appointment or text message. If you miss it or are doing something on the phone you may not get that notification. The Motorola will nag you every x minutes until you push a button. I asked LG support about this. They told me that under notify I can select VIB+REMIND and it will keep vibrating just like the T720. I asked them about RING+Remind. They answered: There is no plan for a ring and remind this change would have to be requested by Verizon. What's up with that?
