Religion and Mobile: a Holy Business

There is about 2.7 billion mobile suscribers worlwide. Less than 2 Billion Christians; about 1.5 bn Muslims, more than 900 mn Buddhists and 15 mn jews, and so many religious confessions worldwide ...
But I unfortunately still can't find an exhaustive religious mobile offer, or any applications / dedicated wap sites on the Eastern Europe operators portals.
I am not religious, but so amazed that one of the main juicy business in the man History still remain unexploited on mobile...

Basically it already exists few Christian softwares for Palm OS, and usual devices ( Handango & Mobizex companies proposes some basic Holy Bible apps); as well in Indonesia a mobile device "certified Muslim" called Hidaya ( = Guidance / good way) already exists , gathering various applications ( sounds alerts for the daily prays, access to Koran, themes, ringtones...);
Also in the US, the "Jewberry", the Jewish-friendly version of a Blackberry, allows the access to prayers in Hebrew, and full texts of Torah.
I think that simple religious mobile nex applications such as geolocalization to find all the nearest saint places... or dedicated mobile communities could easily find his niche on mobile ...and generate huge revenues!
