The iPhone front has been relatively quiet recently, but now we have a new psak with another advancement in the fight against smartphones.

A rav in Ramot, Rabbi Menachem Mendel Fuchs of Ramot D, has issued a psak that will not allow anyone carrying an iPhone (or anything similar) from leading the services in shul (not really new), nor to get an aliya in shul - even if he is the sole kohen present in the minyan (this is new).

Even if this fellow is a kohen, and the only kohen, he will not get the aliyah. Rather, they will call someone else up saying "bimkom kohen" - in place of the kohen [who is not present]. They won't even have to send the kohen out - he will just be considered irrelevant.

We have seen some extreme limitations - not blowing shofar, not leading services, not being a witness to a wedding, etc. but this si definitely a new level.
