The article, translated from the original French version that appeared in the Swiss newspaper Le Matin, notes that these briefs are made with threads of silver which the company claims blocks cell phone rays and reception.
The inventor, Andreas Sallmann, told Le Matin that when you put a cell phone inside your briefs, and then dial your number from another phone, you probably won't even get a signal. Presumably, Isabodywear works with BlackBerry as well.
But here's my question: who in tarnation would ever want to stuff a BlackBerry inside his briefs?
Maybe those regions would come out OK, and that which is just a bit south of your navel would be protected.
But what about your mind? You know, those regions quite north of the navel?
