After the reports of the SMS spoofing security issue Apple released a statement claiming that the iMessage system was 'secure' and should be used to prevent text spoofing. I have received several harassing SMS spoof text messages recently and yesterday I actually received one of the harassing messages via iMessage from a phone number with area code matching my area.
So, is it possible that they sent a spoof text over the iMessage system or was this particular message sent from a legitimate number and iPhone user?
