> I don't think 2100 MHz is close enough to be attenuated by a microwave oven, but of course I'm just speculating because it depends on the design of the oven's shielding. I assumed that the design was that of a Faraday cage, which blocks the frequency it's designed for and all lower frequencies. anotherhue noted however that it's a tuned RF choke, which will only block a certain frequency. For reference, I'm in Australia with a 3G phone on Optus, so the frequencies here are a little less scattered [1].
