Earlier yesterday, it was discovered that the latest Facebook app for iPhone, iPad and iPod touch had the unreleased official Facebook for iPad hidden inside it. Almost every other site on the internet told their readers the procedure to install hidden Facebook for iPad app and it had a catch, jailbreaking your device was deemed a pre-requisite. The following tutorial will teach you how to install Facebook iPad app without needing a jailbreak.
This guide is particularly useful for two kinds of people. First are those who don't want to jailbreak their iPads for reasons best known to them only. Second are those people who have upgraded to iOS 5 beta 4, iOS 4.3.5 or iOS 4.3.4 and didn't save iPad 2 iOS 4.3.3 SHSH blobs. Now they can't downgrade to iOS 4.3.3 because that's the only firmware the iPad 2 can be jailbroken on. Well, that doesn't mean they don't get to enjoy the Facebook iPad app on their tablets.
So before we begin, you'll obviously need to download software that allows you access to the root filesystem of your iPad. i-Funbox for Windows and iPhone Explorer for Mac are two free and awesome software that let you do this. Download either one of them depending on your computer. Google is your friend.
Step 1: Once you have the relevant software downloaded, install and run it. Connect your device to the computer and wait for it to detect your device. Once it does, scroll down in the left sidebar and expand Raw Filesystem. Keep scrolling down until you expand var, followed by mobile and then applications.
Step 2: Once you have expanded applications, it will automatically show the thumbnails of the apps you have installed. Scroll down in the right box and locate the Facebook thumbnail. Double click on it to open it.
Once you double click on it, another Facebook thumbnail will appear. Double click on that to open it as well.
Step 3: Once you've opened it, scroll down and locate the Info.plist file. When you find it, copy it to your desktop.
Step 4: Open the file in Notepad. Make sure you select Word Wrap from View. Locate the following key and integer.
Step 5: Change the value of the integer from 1 to 2.
Save the changes to the file and exit Notepad.
Step 6: Bring up the software again and click on Copy from PC. It will ask you to select the file you want to copy. Select the Info.plist file from the desktop and click on OK. The software will automatically overwrite Info.plist in the filesystem of your iPad.
That's it! Now reboot your iPad and enjoy official Facebook iPad app without jailbreak.
