Free Way to Erase Data On iPhone iPad iPod On Mac

Your iPhone iPad or iPod likely contains a terrifying amount of your personal data: contacts, messages, photos, pictures,  and so on, depending on what types of apps you use, perhaps even social security numbers and bank account information.  Getting a new iPhone, iPad, or iPod touch can be an exciting event, but you’ll want to make sure that you properly erase  your existing iDevice before getting rid of it to protect this valuable information.

There are two free methods of erase iPhone data on Mac: restoring it via iTunes and resetting it via the device’s  settings.

Methods 1: Restoring an iPhone, iPad, or iPod touch via iTunes

First, connect your iDevice to your PC or Mac using a 30-pin or Lightning cable and launch iTunes.

If using iTunes 10 (or iTunes 11 with a visible sidebar), find your device in the source list on left of the window. In  iTunes 11’s default view, you’ll see your device listed in the source bar on the top right of the window. In either case,  click on your device to open its configuration page.

Here, you’ll find information about your iDevice, including iOS version, capacity, battery charge, serial number, and, if  applicable, associated phone number. To erase your iDevice and restore it with the most recent firmware, press the “Restore  iPhone” button. Note that this will completely erase all data, apps, and settings on the device, so make sure you’ve  backed up any data you want to keep before proceeding with this step.

Once you’ve confirmed your choice to restore the device, wait while iTunes downloads the latest firmware from Apple.  Depending on the speed of your Internet connection, this could take several minutes. Once the download is complete, the  restore process will begin automatically. Leave the phone connected to the computer while the restore takes place, which  will involve an automatic reboot or two.

Once complete, iTunes will report that a new device has been found and ask you if you’d like to configure it. At this  point, disconnect the iDevice from the computer; it has now been wiped and reset to factory conditions. You can now sell,  give, or trade the device away for another user to set up.

Methods 2: Resetting from the iOS Device Itself

The steps outlined above for restoring an iDevice require an available computer with iTunes. If you don’t have access to a  computer, you can also reset and erase the device using the Reset feature in Settings.

First, just as above, make sure that you’ve backed up any data you want to keep. Once you’re ready to erase the device,  head to Settings > General > Reset. Here, press “Erase All Content and Settings.”

You’ll receive a warning that proceeding with the reset will erase all data on the device. Press “Erase” to confirm you  decision. Note that users with passcode locks on their iDevices will also have to enter the passcode to initiate a reset.

After you’ve confirmed the reset, the device will process for a moment and then reboot. Once rebooted, you’ll recognize  the familiar iOS setup screen. All of your data and settings will be gone and the device will appear as it did when new,  requiring first-time setup. Don’t enter any information at this point; simply pack the phone up and it will be ready for  sale or trade.

While this method is quick and easy, it does not give you the benefit of updating the phone to the most recent version of  iOS. For most users, selling a phone with the latest firmware is a good idea. For some users who like to jailbreak their  iDevices, however, upgrading should be avoided at all costs, as new iOS versions break jailbreak compatibility. Therefore,  if you know that the person you’ll be selling your iDevice to is interested in jailbreaking, make sure to use this second  method of erasing your data, so that you don’t inadvertently install a newer version of iOS that may make jailbreaking  impossible.

By taking the time to properly erase your iDevice before giving it away, you not only protect your crucial personal  information, you also make the experience better for the next owner, who will get to set the device up with their own  preferences from scratch just as if it were new.

Securely Erasing an iPhone Data Before Selling it

Q: How can I erase data from an old iPhone before selling it, I was concerned when you mentioned that the erasing process “should only take a few seconds.” Does this actually securely erase my data? It seems too quick, and I thought that a secure erase required the iPhone to write over every bit of the memory—in fact I thought Apple changed this years ago in response to somebody discovering that they could get information even off a “wiped” iPhone. I know when I used a tool to “securely wipe” my computer hard drive before I sold it, it took a lot longer than “a few seconds” to do so. I’m very concerned about the confidentiality of my data—is there another method I should be using to wipe my iPhone before I sell it?- Lula

So you want to sell your iPhone. But what if you are selling it to someone you dont know - for example, on Ebay? Do you really want them to be able to recover your personal data that was stored on your iPhone? Things like phone numbers, saved passwords, and favorite websites? No, I didn't think so. Simply use this guide to make sure that even the best hacker wont be able to touch your private files!

A: As we all know, the simple "Delete" is not enough, and "Erase All Content and Settings" doesn't really delete data, because some iPhone data recovery can get them back.
The Erase All Content and Settings option built into the iPhone is definitely a secure erase method, so there’s nothing you need to worry about.

You are correct that the original iPhone did not securely erase user data at all, prompting Apple to change this behaviour in iOS 2.0 to actually do a bit-by-bit wipe of the flash memory—a process that took anywhere from 1-3 hours, depending on the capacity of your device.

To permanently erase iPhone data before selling it,you need to use a third-part iPhone Data Eraser tool. Today, I recommend everyone a useful Data Eraser software,which is a trustworthy and useful software, which designed to delete iPhone data thoroughly, and the deleted data cannot be recovered any more. Due to this extraordinary feature, it become more and more popular among the iPhone users. The most laudable feature is that those data cannot be retrieved again once they are wiped by iPhone Data Eraser, even with any data recovery tool.

However, with the iPhone 3GS and iOS 3.0, Apple introduced hardware-level encryption expressly for the purpose of facilitating a fast, secure wipe process. This was likely inspired by the advent of the “Remote Wipe” feature introduced with Find My iPhone at the same time; it only made sense that if you lost your device, you wanted to be able to ensure that it was securely wiped quickly to prevent the process from being interrupted once it began.

Completely Erase Personal Data Off Your iPhone with iPhone Data Eraser:

• Low (1 pass): erases your iDevice quickly
• Medium (2 passes): no one knows the data on your device is erased
• High (3 passes): meets the DOD 5220 - 22 M standard
This option is by far the most secure data destruction option. It writes over the data 3 times by using the DOD 5220 - 22 M standard. Even a government’s facility with the state-of-art data recovery technology won’t be able to retrieve data afterwards. This mode takes longer but is the safest.

The standard hardware encryption doesn’t specifically protect your data during normal use, since it uses a generated device-specific encryption key rather than anything tied to your device passcode (see iOS Encryption and Data Protection). However, since everything stored in your device’s flash memory is encrypted with this key, all that the Erase All Content and Settings option needs to do is securely wipe the encryption key—a process which takes mere seconds—and everything else in your device’s memory is left as an unintelligible glob of encrypted data, even to somebody who decides to take the memory chips out of the device and forensically examine them.

This hardware encryption has been included in every iOS device released since 2009; even with the latest version of iOS, however, pre-2009 devices such as the original iPhone, iPhone 3G, and first- and second-generation iPod touch still use the old, slower bit-by-bit secure erase method.
