iOS 8.3, which Apple released to general public last week, not only brings 300+ Emoji characters, numerous bug fixes and performance improvements, the software update also prevents 3rd-party file managers and transfer utilities such as iFunBox, iExplorer, iBackupBot, iTools and similar tools from accessing the app directory on your iPhone, iPad and iPod Touch.
The app access change in iOS 8.3 breaks all the file transfer and management utilities available out there for both Windows and Mac OS X. Some fo the developers have already released an updated version of their application with a workaround giving users at least partial access to the sandbox.
In a Facebook post, iFunbox said that iOS 8.3 took away users freedom of controlling the data inside the install apps and games.:
iOS 8.3 ruined our freedom of controlling data in our installed Apps and Games. Apple blocked access of the entire sandbox directory of every installed App since iOS 8.3. Previously only writing is block in executable directory. Now we totally lost the control of Apps on our own devices. We are investigating the situation. Before there is a solution, iFunbox will fail to open data directory of any App if the device is not jailbroken.
iFunBox team was the first to respond to this app access prevention step by releasing a new version with a partial fix. The partial fix, available with iFunBox version 2.95, allows users to have regular sandbox browsing access to all the apps with “iTunes File Sharing” enabled, such as iFileExpress or VLC player. To access all the other apps, user will have to jailbreak the device.
iExplorer developers are still looking into the recent blockade by iOS 8.3:
We are currently investigating how the iOS 8.3 update blocked access to the Apps directory, and we are looking into ways around it. All iDevice transfer utilities seem to be experiencing this exact same blocked access in iOS 8.3, so it’s not just a bug with iExplorer or iBrowse. Apple has definitely changed something with the way apps can be accessed in iOS.
The access change in iOS 8.3 won’t affect the jailbroken iPhone, iPad and iPod Touch devices, because jailbreak enables OpenSSH installation which gives complete filesystem privileges and command-line access. All the users with jailbroken devices will still be able to transfer files between a jailbroken iOS device and Mac or PC. But, keep in mind that iOS 8.3 jailbreak is not available to date and there’s no way to downgrade from iOS 8.3 to an older version after Apple stopped signing iOS 8.2 and earlier iOS versions.
