I saw this page on theRyanair website yesterday, but it seems to have been moved from the main links now and one of my PC's can't open the page correctly either. The link is here but the text is a follows:
RYANAIR IN FLIGHT MOBILE PHONES
Ryanair makes it easy to stay in touch while on the move.
In addition to offering the lowest fares and the best on time record in Europe, Ryanair’s latest offering for passengers now means you will be able to use your own GSM mobile phone for voice calls and SMS during your flight on (subject to regulatory approval). All you need to do is switch on your phone once the aircraft is in the cruise.
Ryanair is the first airline in Europe to announce the fleet wide installation of mobile phone telephony.
Sure, you're traveling, but you still want to be reachable. That's why Ryanair ensures making and receiving calls inflight is easy and straightforward.
The service works just like on the ground, and is billed by your home mobile operator at international roaming rate – you pay no extras!
With your safety being our number 1 priority you will not be surprised to learn that the system we use also manages all active mobile devices on board, ensuring they can never interfere with aircraft avionics or ground networks.
But there's more to this service than just voice. Text messaging (SMS) is cost-effective, quick, discrete - in short, one of the most convenient ways of staying in touch in the sky. With Ryanair, receiving standard text messages on your mobile is FREE! Sending standard text messages is charged according to your home mobile operator and your price plan.
If you're using a BlackBerry®, Treo® or any other compatible Smartphone or PDA, Ryanair will also gives you the freedom to determine the best use of your time inflight.
With a GPRS-enabled device, you can connect to your email or the internet while on the move, and even receive voice calls or text messages while you're online. Ryanair ensures your GPRS-device continues to work in the same familiar way in the air as it does when you're on the ground.
Ryanair’s new in-flight mobile phone service….. just another great reason to fly the worlds favourite airline!
There isn't any date as to when the service becomes live, but it seems to fly in the face of their t&c's which state:
Mobile phones etc
Mobile Phones and Personal Electronic Devices ('PEDs') equipped with wireless phone connections may be carried only in cabin baggage but must be switched off once the aircraft doors are closed for departure. These items must not be used during flight.
