From day one, everyone in my family has noticed that when I start up my phone it automatically sends everyone covered by my family plan (4 other phones) a blank text message. I've looked for a button to uncheck this feature, but none exists (to my knowledge). Last night I mentioned it to my local service rep and they're at a loss. They've heard it happening, even amongst themselves, but don't have a solution.
Does anyone have any experience with this and have you been able to turn it off?

thx ------>JF
