Hello -

I'm writng some software to run on a PocketPC with a built-in GPRS phone,
and I need to test the software when the GPRS signal is weak, intermittent
or non-existent. The cheapest way to do this seems to be to build a Faraday
cage with adjustable leakiness. It needs to have some holes in it so that I
can see the screen and tap it with a stylus. Unfortunately I'm working at a
location that has excellent GPRS coverage.

Simply purchase a new large fridge, and open the door a crack.
