I just signed up for Ting with my iPhone 4s, and everything has been great so far. However I signed in to my dashboard this morning and saw 2 text messages that had been sent to a 4 digit number. I haven't sent any text messages, just a few iMessages (I verified that they were shown as blue and not green) and I had not sent anything at the time shown. Also, they were sent to 2 different 4 digit numbers that I don't recognize. Anyone know what would cause this?
Here's a screenshot from the dashboard:
