I always thought that if a mobile phone was capable of interfering with the performance of an aircraft it would be a prohibited item in the cabin. Simple as. I mean if nail clippers can take someone's eye out and they're way too dangerous to be allowed, a small gadget that can make the entire plane crash is surely more dangerous. Go figure.
However there's never been an incident where a digital camera has caused noticeable interference as far as I know. We just have a big old nanny state in the UK.
Jetset lady a link to a report on ATC interference from mobile phones please? I imagine the Tels engineers are thorough so there should be a few on the 'net.
I have flown Ryanair rather a lot recently as they fly to PIK and no one else does, advice from a Ryanair hosty generally gets a laugh as most of em can't even bark in English. Only airline I've ever flown on where passengers take the piss during the safety demo cos the hosty is hopeless.
