Now that is interesting... Is it the magnetism or the Helium? Be cool to place a iPhone in a helium rich environment and see what happens. I think it was the magnetism, as one cannot breathe Helium well. And after all, Magnetism is a component of RF.
Back in the early days of Digital TV Broadcasting, there was an issue discovered in Dallas Texas in 2001. WFAA wanted to do a test of coverage of Digital HD from their facility late at night. So they got a DTV transmitter for Channel 9 and plugged it into their Channel 8 antenna (it was broadband enough to manage good SWR on 9 for the test, and Harris had a combiner all ready to use from another demo).
They turned this system on on a Sunday morning at like 4 am to see how coverage in DT matched coverage in NTSC.
Every heart monitor system in the Dallas area hospitals went nuts!
Seems that heart monitor systems use low level RF to communicate from the patient to the display. These systems used "white area" frequencies in the TV band and, in Dallas, since the nearest channel 9 is in Oklahoma, the suppliers set the frequency for Channel 9... And since these are Part 15 devices, nobody at WFAA TV knew that they were on the Channel 9 frequency, which they chose precisely because there was no other Channel 9 nearby.
It isn't known if anybody died, but for Belo Broadcasting and Harris, it was a real fun Sunday morning.
Gents, I too am losing interest. Seems that there is a serious lack of brains left in Ham Radio. And it is disheartening.

Awesome article really get you thinking. I have an overwhelming desire to go stick my iPhone in a rich environment.
