A few days ago, Apple released iOS 4.3.4 which is mainly a security update in order to patch a major security exploit found inside the Mobile Safari. Now if you are able to jailbreak your iPhone 4/3GS, 1st-gen iPad or iPod Touch 4G/3G to iOS 4.3.4, you will require a jailbreak tweak that will enable you to sync cracked iOS Apps downloaded through Installous with your iTunes. Well, you will just need to install a jailbreak app called AppSync for 4.0+.
IMPORTANT UPDATE: Hackulous is now officially gone, so you won't be able to download AppSync from the repository anymore. As an alternative, you can use other Cydia repos to download AppSync from: (Best Cydia Repos 2011, Best Cydia Repos 2012, Best Cydia Repos 2013)
Steps to Install AppSync for 4.0+ for iOS 4.3.4 Through Cydia:
- First you will need an iDevice that's jailbroken to iOS 4.3.4. Refer to our Redsn0w guide if you haven't done so. Now Launch Cydia from your 4.3.4 jailbroken iDevice.
- At the Cydia home page, top on the Manage tab at the bottom right of the screen.
- On the next screen, tap on Sources to manage your current Cydia repositories. Now the following steps is for adding the Hackulous repo, so if you already added it, just skip over to step 7.
- Now tap on Edit at the top right of the screen, then Add on the top left of Cydia.
- Now a pop-up window should appear where you will be asked to enter the Cydia/APT URL, key in http://cydia.hackulo.us, then just tap Add Sources when you are done.
- Cydia will now download the Hackulo.us repository and will updates its database of sources, so give it a few seconds. Once the process is complete, you should be given an option to Return to Cydia, so just tap on that.
- Now you should be back to Cydia's main page. We will search for Appsync for 4.0+ by tapping the Search tab below the screen. Just type Appsync into the search field and the app should appear in the results.
- What you need is AppSync for 4.0+ so go ahead and select it. On the details screen, tap on Install located in the top right.
- Now Cydia will be installing AppSync in your device so just sit back and relax. Once the installation process is finished, a Return to Cydia button will appear so just tap on that. And that's it, you are done. Just install Installous so you can download and install cracked iPhone apps.
NOTE: If you are unable to add the Hackulous repository into Cydia or you do not have WiFi access, then you can still Install AppSync offline. Just download the needed DEB files here and refer to this guide on how to install AppSync for 4.0+ with or without SSH access.
