Apple announced iOS 5 at WWDC 2011 earlier this year. We’ve been testing out betas of iOS 5 but know for sure that public iOS 5 release is no more than a month away. So with that on the horizon, the guys at Hackulous have released AppSync for iOS 5 and above. You can now download AppSync for iOS 5 for your iPhone, iPad and iPod touch.
If you do not know about AppSync, either you’re new to iOS jailbreaking or you have been living under a rock with your jailbroken iPhone, iPad and iPod touch. So before we jump in to AppSync for iOS 5 download, here’s the low-down on AppSync and its working.
Basically, AppSync is a system tweak that you can install after jailbreaking your device. It alters how installd works on your iPhone, iPad and iPod touch. Installd is a part of the iOS firmware and its task is to manage the installation and compression of apps on your device. To install cracked apps on iOS device, you need Installous because it bypasses the DRM signature check that installd does with Apple. Installous is also a creation of the Hackulous team and it too alters how installd works on your iDevice. To install AppSync and Installous, you need to jailbreak your device. If you don’t have these two system tweaks and try to install cracked apps, installd will run the DRM signature check with Apple and due to the fact that you have not purchased the app from the App Store, it will return an error saying that installation of the app is not possible.
So if you have Installous you’ll be able to install cracked apps on iPhone, iPad and iPod touch, but what about syncing them and copying them to iTunes for a backup? Here’s where AppSync comes in because it creates a backup of the original installd, saves it and replaces it with a new installd that does not run DRM signature checks with Apple and allows you to sync all of your cracked apps with iTunes on your computer. AppSync just patches the original installd and won’t affect legitimate app downloads from the App Store in any way.
Coming back to AppSync for iOS 5, previously when we tested iOS 5 beta firmware, even did a jailbreak and installed both Installous and AppSync, they used to work fine. The previous update to AppSync was done when iOS 4 was released and subsequently Hackulous released AppSync for iOS 4 and above. Now it has been seen that in the latest iOS 5 beta firmware, Apple has begun packing installd binaries so AppSync for iOS 5 download had to be made available. AppSync for iOS 4 was compatible with iOS 5 beta firmware but now the Hackulous team has released an update of AppSync for iOS 4 which limits its use to iOS 4 and above only.
Remember: Once you install AppSync for iOS 5 on your jailbroken device, don’t forget to reboot it so that installd is patched successfully. After reboot, you have to install a free app from the App Store before installing cracked apps and backing them up to iTunes. If you do not do this, your apps will automatically be deleted from iTunes.
So for example if you are running iOS 5 beta 7, you must follow this tutorial for iOS 5 beta 7 jailbreak and then you can install AppSync for iOS 5 and Installous from Cydia.
