Have been googling this, but can only find old and contradicting info, so am wondering if anyone has the definitive answer? I need a text that was sent to me over a year ago for a potential lawsuit. It was received on a 1gen iPhone, which at a later point has been restored/had the firmware changed. I do not have an old backup of the phone in iTunes from the time when I got the text. Also, I was using a prepaid Vodafone SIM at the time if that matters. Cheers.
