We might have a nasty case of selection bias here, though:

Misuse of Bluetooth technology by young men and women is increasing in Saudi Arabia. A recent study found that pornographic material accounted for nearly 70 percent of messages exchanged by teenagers. Abdullah ibn Mohammed Al-Rasheed, associate professor at the College of Dawa and Information in Riyadh, who conducted the study, said 88 percent of girls had been victims of such misuse. Rasheed presented his study at a seminar organized by the King Fahd Security Academy. The study focused on teenage boys detained by the Commission for the Promotion of Virtue and Prevention of Vice for harassing girls in the Qasim region.

“The flash memory of mobile phones taken from teenagers showed 69.7 percent of 1,470 files saved in them were pornographic and 8.6 percent were related to violence,” said Rasheed. About 99.2 percent of people surveyed, mostly students, military officers and businessmen, used Bluetooth in public gatherings.

Hard to tell if the 70% figure is based on all teenagers or just that demographic of busy-hand boys that the study “focused on.” As written, it sounds like it’s the former, especially since they also surveyed teenaged girls. Speaking of which:

Ninety-nine percent believed that the device had broken the barrier of social taboo and traditions. About 77 percent of girls admitted that they had used Bluetooth, even inside the Grand Mosque in Makkah

Exit question: How useful will technology like this ultimately prove in opening up cloistered societies?
