My BFF since high school (too long ago to say lol) called me over  the weekend hysterical crying because she has pretty good evidence that her husband of 24 years is having at least one homosexual extra-marital affair.  She would very much like to get physical evidence in order to confront him,  She found out he has a "secrect" iPhone and would like to see if she can snoop through it and get information on emails, text and browsing any suggestions?  She can descreetly get physical control of the device.  She read about a few devices that can read a sim card but she wasn't sure if they work.

Thanks for any help anyone can provide.
