Has anyone tried this using an iPhone? My wife just got an iPhone (so I'm not familiar with the device). I registered it in the Beta/SMS Controls tab of VPanel, made sure it was toggled green, then sent "voipo1 dnd voicemail" to 95495. I used "Messages" on the iPhone, which I assume is the SMS application. Nothing happened.

I then used my cell phone (which is registered to my Add-on line) to send the same command to the same number, and it worked fine.

The only thing that was odd about the iPhone was that when I entered the number "95495," the phone converted it to "95-495." Is there some special way to enter 5-digit SMS addresses on the iPhone?
