Interesting! As I recall both BMI and TAP (?) were "boasting", I think it was almost 2 years ago now, that they were about to allow use of mobile phones on their flights. The plan never came to fruition as there was an outcry on at least several forums. It is bad enough having the peace and quiet of the lounge disturbed by the needless yelling into mobile phones without the same thing happening in the air.
Anyway you can be sure that if money is to be made Ryanair will be first to allow mobiles as soon as they can obtain certification for their Boeings; then all airlines will be at it!
Enjoy the peace in the air whist you can.
Hmm... can we obtain and use electronic "blockers"?
