Remember when cell phones were just used for calls? Now, they're mobile messaging machines. Every day, fast-fingered customers send millions of text messages through their phones. And while many use their thumbs to type out rapid reminders; it's all too tempting to get into conversations, true confessions, even arguments.
Fine and good, except -- did you know that cell companies keep those things?
"It's a lot like e-mail. When you delete an e-mail, you think it's gone--out of sight, out of mind. But that's not the case," says John Walls, who speaks for America's cell phone companies.
"They keep those messages on hand for billing purposes, if you have a question about 'Did I send that message?' 'Yes, you did send it' or 'No you didn't, we made a mistake and we're going to correct that.' "
But why would they keep the message itself? The words you typed, or the picture you sent? U.S. Cellular cites customer service. Its website lets you read old messages and view your pictures.
"If there's a network outage of some type and people say, 'Hey, re-transmit those to me, I haven't had an opportunity to open them,' it's a customer service issue."
It's also become a tool for law enforcement. The Army used text messages to court-martial Ryan Anderson. He thought he was selling secrets to Al Qaeda, but was really writing to undercover agents. Kobe Bryant's defense attorneys were able to read text messages sent by his accuser, in the hours after she says she was raped.
These strings of letters and numbers are being pulled off phone company computers and used in courtrooms across America: a murder case in Oregon, a kidnapping in Missouri, in Los Angeles, a city hall corruption probe.
In other words, scenes like this --
"You've got two months of text messages in this file?"
"I do, if you've got a warrant."
-- aren't only happening on television dramas.
It's not nosy; it's actually the law. And police aren't the only ones who can get court orders. Divorce lawyers are using text messages to prove infidelity. One school principal used them to bust students who cheated on exams.
"Probably the biggest lesson is 'keep your nose clean,' " says Walls.
But phone companies say you shouldn't worry about "just anyone" grabbing messages out of thin air: they're safely encrypted.
"There is no other means, no other way to go about receiving or obtaining that kind of information concerning a customer's account," Walls explains.
Just how long do these messages stick around? We surveyed Chicago's most popular cell phone companies. T-Mobile told us it doesn't save messages at all. AT&T holds them for three days. U.S. Cellular, for five. Cingular stores messages for a week. Verizon waits ten days. And Sprint PCS? A whopping two weeks.
None of the companies said their contracts or privacy policies address the issue. A U.S. Cellular spokesman said it's posted on the company's website. But even he admits: it's not very clear.
Some obvious questions come to mind. Does this mean employees of wireless companies can browse your messages at will? Not really. The companies have strict passwords and watch for potential snoops.
But on the flip side, even though a company says it gets rid of messages after a week or two, some high profile cases prove: they're rarely erased. Prosecutors have successfully subpoenaed text messages off company hard drives that were months old.
