Mobile phone ok to use unitl doors closed then totally switched off, not to be used in flight mode at all! also shouldnt be used when walking from/to aircraft/terminal via the ramp (i.e no airbridges as at EMA)
Blackberrys as above however ok to use only in flight mode and only when seat belt sign switched off! (when sign is on it must be completely switched off)
Just for clarification is that exclusively Blackberries or are other smart-phone devices allowed to be used as well? Any of the Nokia N series phones or the iPhone, several Samsung and SonyErricsson devices,etc have the same functionality as a Blackberry and similar "flight safe" mode.
