According to a survey conducted by marketing agency 11mark, about three-fourths of Americans with mobile phones admit that they have occasionally used their devices in the bathroom.
74 percent of men and 76 percent of women reported that they took their mobile phones into the bathroom, so there wasn't a large gender gap. Instead it was their device types which divided the toilet texters (and talkers) from those who prefer to disconnect while in the lavatory.
The BlackBerry users were the ones most likely to answer a call than the others though. According to the survey, "75 percent of BlackBerry users report they have done so, versus 67 percent of Droid and 60 percent of iPhone users."
I hope they at least hang up before flushing.
