Any truth in the rumour that cell phones can corrupt eproms?
I always have my digital cell phone in the area where I work on my PICs.
No problems yet (well not that I know of).

But I ask just to be safe.

 And *never* use them in a dairy herd - it'll curdle all the milk!

Purely theoretically speaking, if you attach lambda/4 wires to the proper
pins of an EPROM and manage to get the phasing right between them then a
nearby (10 cm) GSM phone should be able to induce enough energy in them to
corrupt some cells (if running on a high Tx power setting). It takes MUCH
less than 0.6W to reprogram an EEPROM bit or word, and the 0.6W is average
power where pulsed power is higher.

I suppose that if the dairy workers talk long enough it might as they're
bound to forget to shut some valve or switch at the end of the day/run.
