So I have a jailbroken iPhone 3G. It has always worked perfectly until recently. When I receive texts from friends, every once in awhile (probably every 4th text or so), the SMS will be received but instead of displaying the SMS from my friend, it will display a PREVIOUS MMS that I'VE sent from a couple weeks or months ago. So I can't read my friends SMS messages bc it displays as an old MMS of my own. This is so frustrating asking my friends to RE-TEXT stuff every 3rd or 4th text. This is so weird. I tried searching but found other stuff about MMS texts, but nothing about this odd receiving error. Thanks in advance.
