The one thing noticeable when people are taking pictures with their
camera phones is that they don't use a flash. You would want to be
sure you had the flash set off prior to taking any pictures.
Some of the latest cell phones take video too (albeit still poor
quality) - I wonder to what extent they might try to ban that, although
you would only be able to take a short clip with poor quality.
Off topic though, the coolest thing I have seen lately is an update to
those songs where the house lights would dim and people would take out
their lighters - now everyone takes out their cell phones - it's pretty
awesome to see a couple of thousand cell phones illuminating the venue
at a concert...
