This is not limited to hacked or jailbroken phones, but also includes expensive "officially supported" factory unlocked phones. To make the problem worse Apple has made it impossible to downgrade back to working 3.0 version for iPhone 3GS phones."

You do sounds a bit paranoid to me, but that is a problem to be solved as well.

A simple cable tester could be foiled by a hardwire tap. My best bid at checking for such a tap would be to measure impedance of each connector at various frequencies and compare those numbers to those of an identical cable. If you can get an advanced cable tester that output results as various electrical properties, then that should do the trick as well.
