On every staff familiarisation trip I've been on, it has been emphasised that taking photographs, whether by camera or mobile phone, is strictly prohibited.
This is bacause, at the moment, the Flagship Terminal is very newsworthy and BAA, who own the building, wish to control exactly what pictures appear in newspapers and magazines.
There are some outstanding pictures on BAA's website and on ba.com and if you wish to illustrate any items on this forum, feel free to provide links accordingly!

www.baa.com is the full address in the address bar of your browser!)
