Given the iPhone is a sealed unit...
If only it were. These things can be taken apart with ease. What our friends in security are apparently looking for are devices where certain components have been swapped for less benign ones. But whose electricals will they be checking? Discrimination is not their strong point. The trouble is, your average security bod is unable to determine a good guy (Police Officer, Customs Officer, law abiding passenger, catering staff etc.) from a bad one (nasty terrorist, security guard) etc.). On minimum wages, they won't be able to attract staff capable of doing so either. Therefore, they treat everyone with the same contempt. And what do we get in return? Peace of mind? Value for money? Security?
