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.
