Weird Text message Problem

[mebo73]

So last night i was texting my friend for a while. Then all of a sudden she asked me why i keep sending a certain text to her. I told her i wasnt. She told me that she had recieved 16 text messages of the same text. Prior to texting her Installed HARVEYS internet fix and the MMSMESSAGE HACK. But that was way before this certain text. So I talk to her this afternoon and come to find out she has been sent this same text message for 46 times. She called AT&T and they said it wasnt her phone. SO... I find out that the certain text was in my outbox, I tried deleting and it wouldnt delete. I tryed doing a soft reset to see if that would get it to go away and still nothing. I ended up having to DELETE all my text messages in my inbox and in the sent box. She said it stoped, This was just really weird. Wanted to tell everyone and wanted to see if anyone knew what caused it.
