Don't think in problems, think in solutions
Why is every-one so crazy about this antenna thing?the solution for apple is very easy. What they should do is to split the antenna (the metal frame) into two separate pieces wired and connected from the centre. If you place one hand on the left and one on the right, there will be no connection, hence no problem with the reception. Because the wirering is done from the centre of the phone (one wire to the left, one to the rigt) there can never be a "tough" of the antenna which causes the connectivity to decrease.
Does it really need a Dutchman to come up with this?
