Q:

Will one get in trouble for taking a jailbroken device through airport security?

My brother is worried that he may get in trouble if the people checking bags at security can see his jailbroken device when he enters the US. 
Are there any documented cases or specific experiences with this where people got into trouble due to a jailbreak modification?

A:

From me, a US citizen, I wouldn't worry about it at all.
They shouldn't even touch his iPhone/iPod, let alone turn it on. Also, I can't imagine how he could get in trouble over something that is legal in the US (jailbreaking). 
From my experience flying, electronics are just sent through an xray machine. Any search of electronics would make people upset on grounds of the 4th amendment.

A:

I work for the TSA and no, we cannot see that the device is jailbroken, nor do we care that it is jailbroken...
