Very kinky. Had my iPod and mobile phone laying next to each other on the desk. iPod is playing my favorite Dire Straits. Phone rings. Also vibrates. iPod freaks out... volume jumps all over the dial... backlight flashes on and off... sound is all choppy... when I answer phone, iPod goes back to normal... volume is lower but I turn it back up and all is OK. How bizarre, how bizarre.
Hmmm, strange one, but not uncommon for mobile phones to interfere with electrical devices - hence the reason you can't use them in hospitals & whatnot. Thanks for the post though!
