Sometimes my work Blackberry calls people from my purse, it somehow latches on to either the contacts list or calls I’ve made and calls the numbers back. It must be from getting jostled around. My friends or colleagues will get a call and here background noises, or me talking to someone else in person. Weird. I also had to disable the function that assigns shortcut keys to people’s names, as just hitting one key would instigate a call. Still, the calls from the train are very stramge, indeed.
No mystery here. Just complicated electronics that do not like water or fire foams. Wet three numbers and it dial three contacts in what ever order you have them in. Wet 6...Wet 9 or all.
