I haven't seen it myself, but I was told that there was a "MythBusters"
episode where the guys demonstrated that certain cell phones interfere
with
the ILS, causing the needle to deflect at least 50' to one side of the
runway.

I did see it. First, you have MUST keep in mind that the experiment,
while planned and controlled, was NOT realistic and the results were
inconclusive.
With that said, the receivers were cobbled together from off-the-shelf
from used avionics components. The system, under "normal" operation, with a
"normal" cell-phone did nothing to the glide slope or OBS. It was only when
the cobbled-up ILS was subjected to boosted energy on the cell-phone
frequency that some deviation occurred.
Note that the experiment ended up with a BUSTED! conclusion and caveats
from Jamie that the Mythbusters proved nothing.
