Your iPhone is spying on you while you sleep.

No one saw this coming. No one.

The Jeff Bezos Peoples' Republic via 9to5Mac: Washington Post finds 5,400 app trackers sending data from an iPhone.

Monitoring software used by The Washington Post on an ordinary iPhone found that no fewer than 5,400 app trackers were sending data from the phone – in some cases including sensitive data like location and phone number.

    "It’s 3 a.m. Do you know what your iPhone is doing?

    "Mine has been alarmingly busy. Even though the screen is off and I’m snoring, apps are beaming out lots of information about me to companies I’ve never heard of. Your iPhone probably is doing the same — and Apple could be doing more to stop it."

The same story at OregonLive mentions one additional detail not noted in the above article:

[My iPhone] was receiving a message that included my IP address -- once every five minutes.
