Sorry, Keef, but licences for home radios were abolished in 1971. There is no such thing as a "blanket" licence. There are exemptions for some devices such as WLAN, bluetooth devices, car remote central locking devices, etc.
Fuji, I am sure you are correct that the phone is approved by EASA. That does not mean that it is approved or licensed by OfCom, who have responsibility under the Wireless Telegraphy Act. Not all rules and laws that cover what goes on in an aircraft are contained within the ANO or CAA regulations. It is illegal to murder your wife in an aircraft, but that law does not appear within the ANO.
Katamarino, you may be sceptical about the ability to petition to change out-of-date laws. That does not justify breaking them.
