Well i upgraded to the att 4.5 OS a couple days ago and today while my phone was sitting on my table i start receiving txts saying "what do u mean".... and everybody said I had texted them saying

"Id Back"

Im positive no one did it because i was the last to use my phone to txt someone.... what makes it crazy is that its not in my sent box....

i have not a clue what to do or stop this... its really tripping me out...

any help is appreciated
