According to apple, this new iOS firmware iOS13.3 Beta 4 is now prepared to fix the latest icloud bypass method from removing or renaming setup.app folder. This icloud bypass is possible because checkra1n jailbreak tool open the SSH communication between mac computer and iphone or ipad. Apple is trying very hard to avoid this method. In the end of the next week, apple pretends to release the new iOS13.3 to fix this and other bugs and leaks created by checkra1n. We all know this setup method is very limited, the device is not full unlock you can not use the phone to make calls cellular data and activate your device with iTunes, but you can still make very good use of your device.
If your device is icloud bypassed STAY AWAY FROM iOS13.3 UPDATE and save shsh2 blobs.
If you pretend to keep your icloud bypass device with working apps and be able to use safari, email and many other apps you should stay away from this version iOS13.3 or UP.
NOTE: Apple is also fixing the possibility of using an Apple ID from an activated device and upload the files into the icloud bypassed device. replacing these files you will be able to download apps from AppStore and activate the notifications.
Meanwhile, in iOS13.3 update you still can remove setup and be able to icloud bypass but will only jump into the springboard. will not be possible anymore to open apps. It will be just a bypass of the icloud lock screen and the phone will still be useless.
