You are certainly allowed to just do a regular upgrade, but you won’t get data protection (and if you’re in an enterprise, know that configuration profiles can check against this as a pre-requisite.) And for those on earlier hardware – sorry, you lack the hardware chip to do the encryption.ĭevelopers who are interested in the technical details or in leveraging Data Protection should check out Session 209, “Securing Application Data”, in the WWDC 10 videos. You will need to set a passcode to get the benefit of this (but you should have that anyhow) iPhone 4 users will automatically have this out of the box. ![]() You can confirm this has been done by going to Preferences -> General -> Passcode Lock and scrolling to the very bottom, where you should see “Data Protection is enabled.” Wait the somewhat lengthy amount of time as all your data is put back onto your phone. ![]() When the installation is done, iTunes will prompt you about restoring from the backup you just took.Let iTunes download the installer and do a complete restore.Rather than clicking “Upgrade”, click “Restore”.So if you have an iPhone 3GS or iPod Touch 3rd Gen, you need to do a backup-factory restore-data restore installation of iOS 4. ![]() Sounds great, right?

From my understanding, Data Protection is meant to correct some of the issues with the original hardware encryption method introduced last year on the 3GS and 3rd Gen iPod Touch. One of the new features in iOS 4 that has been underreported on is called “ Data Protection“. But before you go rushing to update your phone, let me give you one small piece of advice:Īpple has done a great job bringing some of the enterprise security features (complex passcodes, wipe on 10 failures, etc) to regular users as part of the upgrade. But since Apple’s mobile operating system wouldn’t allow an app like Vivid to run on the system, the developers have created a web browser that can also. He's been gaming since the Atari 2600 days and still struggles to comprehend the fact he can play console quality titles on his pocket computer.For all of my friends and readers with existing iPhone/iPod Touch hardware, today is an exciting day: iOS 4 is now available via iTunes.

Having grown up using PCs and spending far too much money on graphics card and flashy RAM, Oliver switched to the Mac with a G5 iMac and hasn't looked back. At iMore, Oliver is involved in daily news coverage and, not being short of opinions, has been known to 'explain' those thoughts in more detail, too. ![]() He has also been published in print for Macworld, including cover stories.
