(CNN) -- News that iPhones and iPad 3Gs apparently collect continuous information about the whereabouts of their users and store that data in a secret file has lots of Apple fans worried about their privacy.
Two researchers on Wednesday unveiled the details of this secret file, called "consolidated.db," which stores location info going back to June 2010. That's when Apple updated its mobile operating system, called iOS, to version 4.0.
Apple hasn't commented on these allegations, and it appears the company does not have continuous access to this location data, according to the researchers, one of whom says he is a former Apple employee.
All of this may be confusing for iPhone owners, especially since this news terrifies some and seems like a lot of fun to others. To help clear things up, here's a quick round-up of what you need to know about iPhone tracking and your security:
How does the iPhone collect this location data?
It uses cell phone towers to triangulate an approximate location. This isn't as accurate as GPS, which uses satellites to pinpoint a phone's whereabouts.
How often is a location recorded?
At seemingly random intervals, but fairly often, according to Pete Warden and Alasdair Allan, the researchers and journalists who publicized this secret location file.
Where is this data stored?
On the mobile device and on the computer the device is synced to.
Who has access to it?
In theory, only you. Apple does not appear to have access to this data, at least not on a real-time basis, according to the researchers. So it appears the company doesn't know where you are right now.
Mobile phone companies also collect this type of data, but, as the researchers point out, that data "normally requires a court order to gain access to it, whereas this is available to anyone who can get their hands on your phone or computer."
The location file is unencrypted, so anyone with access to your phone or computer could, in theory, get access to it and know where you've been. The researchers, in their report, say Apple has "made it possible for anyone from a jealous spouse to a private investigator to get a detailed picture of your movements."
Could someone steal this data?
It's possible someone could look at this file and know where you've been since June. But they would have to gain access to your phone or your computer, where the consolidated.db file is stored.
The researchers see little risk in this, but they note that there are more questions than answers when it comes to who can see this stuff and why it's collected and stored on phones and computers in the first place.
They write: "Don't panic. ... There's no immediate harm that would seem to come from the availability of this data. Nor is there evidence to suggest this data is leaving your custody. But why this data is stored and how Apple intends to use it -- or not -- are important questions that need to be explored."
What if I want to see a map of all the places I've been?
Some people are having fun looking at maps of where they've been over the course of 10 months. The researchers who publicized this file also created an open-source program called iPhone Tracker, which is free for download and can be used to create a map of everywhere you've been since the tracking started.
Which gadgets collect this location info?
Only iPhones and iPads that have 3G connections and have been updated to operating system 4.0 or later. To see which version of iOS is running on your phone, click on the "Settings" app, then choose "General" and then "About." Halfway down the page you'll see a number next to the word "Version." That's the iOS version that's currently running on your phone or iPad.
It's unclear if this type of file is stored on iPhones on Verizon's network or on Android smartphones. The researchers say they're looking into it.
Can I stop this information from being collected?
It's not easy. You can delete this data from your computer, making it less likely a hacker or trolling family member would access it.
To find the file, follow this pathway on your machine: /Users/Library/Application Support/MobileSync/Backups/
But, the researchers warn, this file will be updated again every time you sync your phone to a computer. So deleting the data is an arduous task.
People who jailbreak their phones -- read more about jailbreaking here if you're not familiar -- can download a new app called Untrackerd, which claims to delete the consolidated.db file as it's created. That app is available from the Cydia app store, which is not sanctioned by Apple.
What else can I do if I'm worried about this?
The researchers suggest encrypting your data through iTunes. This makes it more difficult for anyone with access to your computer to steal this data.
To do this, open iTunes, plug in your iPhone or iPad and click on the device name when it shows up in the "Devices" category on the left side of the screen.
On the device's home screen, scroll down to the "Options" menu and click the box that says "Encrypt iPhone Backup."
A note from Apple on this: "Encrypted backups are indicated by a padlock icon (as visible below in the Deleting a Backup section), and a password is required to restore the information to iPhone."
Is everyone upset about the tracking file?
No. Plenty of people, especially in the tech elite, think it's fun to use the iPhone Tracker program to see a map of where they've been recently.
They point out that cell phone companies already collect this data. This just makes it accessible to users, if they want to see it.
Who discovered this file and how did they do it?
Allan and Warden, two researchers and writers, say they came across it while working on a data visualization about the Japan earthquake.
From their site: "We'd been discussing doing a visualization of mobile data, and while he was researching into what was available, Alasdair discovered this file. At first we weren't sure how much data was there, but after we dug further and visualized the extracted data, it became clear that there was a scary amount of detail on our movements. It also became obvious that at least some other people knew about it, but it wasn't being publicized."
They also posted a video about the experience.
They're not the first to come across this, but they were the first to grab the public's attention with this information. Some bloggers have pointed out that other versions of Apple's iOS stored similar files, but they were harder to find.
Why would Apple collect and store this info on phones and computers?
It's unclear. The company hasn't commented. But some bloggers and the researchers themselves speculate they could be looking toward future applications for phones. From the researchers:
"One guess might be that they have new features in mind that require a history of your location, but that's pure speculation. The fact that it's transferred across devices when you restore or migrate is evidence the data-gathering isn't accidental," they write.
Did they share this information with Apple?
The researchers say they did, but they haven't heard back. Apple has not responded to CNN's requests for comment, either.
U.S. Sen. Al Franken also has written a letter to Apple expressing concern and asking for answers to a few key questons about this file, such as why it's stored in an unencrypted format.

내 젊은 시절에서울구치소에 한100일 정도 법무부 신세를 진 적이있다. 그 때 한 방에 있는 청도 얘가 제법 잘낭 척 아주 자주 가끔은 오는 단골인 것처럼 행동을 하고 있었다. 어느 날 얘기 중에말한 어떤 사건이다. 어느 외딴 곳(섬이었든가 분명치가 않다)에서 일어난 일인데 아들이 엄마를 겁탈하고 그 흔적증거를 없애려고 집에 불을 놓아 함께 태워버렸다고 한다. 도무지 믿어지지도 않았었고 아직도 설마 그런일이 일어날려구라고 생각 한다.
서울중앙일간지 사회면 톱을 가득 채우는 엄청난 교통사고 후. 깨어났을 땐 사고 후46일이 지나있었다. 뭃론 난아무런 사정이나 어떤 정황도 전혀 알수도 기억해낼 수도없었다. 어쨌거나 교통사고가 났었고 46일이 지났었고 함께 탄 사람은 현장에서 죽었고 여기는 신촌세브란스 응급실이라고 했다. 그러하건만내겐 아무런 느낌이 없었다. 어쨌거나내가 의식을 찾은 바로 그 순간 나는 저승 사후의세계에서 돌아왔다. 물론난 종교가 없었다. 종교는 할일 없는 한가한 놈들이나 하는 짓거리 정도로 알았었다. 여튼 나는 사고 후 의식을 잃고 coma상태에서저 세상으로 갔었다. 그런데 저 세상의 관문에서조선시대 포졸들의 유니폼 같은 옷을 입은 관리가문 앞에 도달하여 두리번거리고 있는 나를 향해 넌 왜 왔냐라고 물었다. 허리를 낮추고 엉거주춤한 자세로 우물우물하고 있으니 장부를 집어들고 펄치더니 야 임마 넌 아직 올 때가아니야 돌아가 했었고 바로 그 순간 내 눈 동자로 세상의 빛 전기불이 흐릿하게 느껴졌었다.
세상의 외딴 곳에서 일어난 일을 얘기해도 못믿는 세상과 인간들에게 사후의 세계 저승을 얘기하니 누가 이걸믿겠나. 그러나 한가지 분명한 것은 우리 너와나 인간은 꼭 한번은 "돌아간다" 죽는다. 바로 왔던 그 곳 저승 사후의 세계로 말이다.
내가 행동한 활동의동선이저장기록된다고들 온 지구가 들끓고 있다. 그게 그렇게 중요한가. 그럴수도 있다 그러나 실제로 이는 단지 주변적peripheral인 일일 뿐이다. 너와나 우리 모두가 하는 행동 뿐 아니라 마음 속의 모든 생각까지도 매 순간순간 하나 빠짐 없이 하나 같이 다 기록되어지고 있다면 머리 끝이 쭈빗하지 않으신가요. 인간이면 꼭 돌아가야만 하고그 곳 사후세계 저승에 있는 거대 컴퓨터는 우리 몸 속에 세계 유일의 정교한 컴퓨터에 접속되어 모든 언행심사 어느 것 하나 빠짐 없이 다 기록하고 있고 또한 기록되어지고 있다.
그러나 안심하십시요. 창조주우주신God는 아주 공평합니다. 사후를 위해 이렇게 모든 것을 다 기록할 뿐만 아니라그 반대 급부로성공이란 위대한 목표달성을 위해 너와나 우리의 시간과 공간의주변에 무수히 많은크고작은 단서와 흔적을 남겨 놓으셨습니다. 깨어있는 통찰력, 머리두뇌를 거두어 들이고 본래의 마음, 태초의 마음으로단순해저 있으면 성공을 거뭐질 성공의 확실한 증거흔적단서가드러나지게 됩니다.
온 지구가 Easter holiday축제로 뜨겁다.
