I am having the weirdest thing happen to my iPhone 4S i have ever seen before. Its almost like its a virus! There is a test message in my inbox that just said "Unknown" and nothing more. It keeps coming back, have reset my phone, deleted it, deleted all messages, wiped inbox, etc. please see pics below. When i go to the Messaging app I see this (note the one that says Unknown) now I delete the message, and you see that its gone below: I now go to the home screen and then open the messaging app again.... and boom, its right back there. It does not matter what I do, its keeps coming right back.... This is what it looks like if I open the message... there is not there..
