But I thought that this vulnerability was in the hardware, not in any 
particular apps that may have been installed. My wife's phone is white 
whereas mine is black, so even though were bought only days apart they 
could very well have significantly different manufacturing dates and 
different chip revisions.

Why did the August update apparently introduce a new vulnerability in 
mine, and why does the Check Point Scanner give a different result on my 
phone from QualComm's own?
