How to install Facebook App on your old iPhone 3G iOS 4.2.1

This video will show you how install Facebook App on your old iPhone 3G.

So I after I did the tutorial on how to jailbreak your iPhone 3G running iOS 4.2.1 see the video here.
I had a few people ask me how to add Facebook to the old version of the iOS and this is how you do it.

NOTE: You must first Jailbreak your iPhone see the link above for more detail.

Step 1. Open Cydia on your freshly jailbroken iPhone 3G.
Step 2. Press Manage > Sources,
Step 3. Press the Edit than Add button.
Step 4. Type and press Add Source.
You should then have iPhone under your Sources.
Step 5. Press iPhoneCake
Now here is the important part. You need to select the AppSync version for your iOS.
Since my version is iOS 4.2.1 I will need to select AppSync for OS 4.2.
Step 6. Select AppSync for OS 4.2.
Once you select it properly it should have a green tick beside it.

Ok, you are halfway through stay the coarse and you will be rewarded 🙂

Step 7. Download file from the 123myIT downloads webpage here.
iTools is an application which allows you to place apps directly on your iPhone. This is the tool that we will use to get the old version of the Facebook app on to your iPhone.
Step 8. Extract the file to your desktop.
Step 9. Run the iTools 2012.exe file.
Step 10. Connect your iPhone to your PC and give the PC time to install the iPhone driver. Once its installed it should look like the screen shot below.
iTools 2012
Step 11. Download the Facebook App from 123myIT Downloads page here.
Step 12. Extract the Facebook App file to your desktop.
Step 13. Go back into your iTools 2012 application click on application inside the iTools then simply drag and drop your Facebook App file that you extracted to your desktop.

This should load your older Facebook app back on to your iPhone. Simply click on it login with your Facebook user name and password and you are ready to go. 🙂

I hope this helps you out. Please leave some feedback and thumbs and share this page with your friends if it helped you out.
Newer versions of the Facebook apps can be found on Google Play and iTunes app store.

Good Luck 😉

    • Hi Dave
      I had a look for this app but when I tried to download it the links would time out. I am not sure it would be worth it anyway because I came across a page review for it and it said it got pretty bad reviews???

    • Hi Hamza
      The only suggestion I have is to do a backup of your data and then restore your iPhone back to factory settings and repeat the process. Otherwise you can try the Whited00r 6 firmware which has the Facebook in the App Market.

      At any rate here are the videos to help you.
      Facebook install.
      Whited00r 6.

      Good luck. Let me know how you go.

  7. I tried to step 7 but it has problem. When open itool 2012, it requires to update then I update but it has notice “iTools 2012.exe has encountered a problem and needs to close. ” . I tried many time but couln’t. Pls help to fix it.

  9. hi there, it helped, but wasnt quite what i was looking for. Apparently i cant seem to fina any normal way to install skype to iphone 4.2.1. Any advice?

    • Hi Irena
      You can install Skype via Whited00r 6 I know this works as I have logged in and tested it myself.
      If you don’t want to go that far with the firmware I will see if I can fix it using the 4.2.1 firmware and let you know.

  10. Hi! I just installed the messenger on my 3G the way You instructed us to do, everything went well but… when I logged into the messenger, there’s a communique saying sth like “To use Push notifications, connect to iTunes. Notofications for “messenger” can be communiques, sounds and badges on icons” (not sure how would it be in english, I use polish in my 3G). The communique is impossible to close (it has OK button but it appears again right after pushing the button) 🙁 What should I do?

    • Hi Paul
      Did you Jailbreak the phone? and did you set the App Sync via ?
      If you did and then it is still not working I suggest that you do a:
      * backup.
      * Restore
      * Jailbreak
      * Then run the Facebook messenger again.

      Good luck 🙂


      • Yep, my iP is jailbroken already. I simply turned off the notifications for apps in the main settings menu, it works now 🙂 Of course notifications don’t work anymore but I don’t find them extremely helpful anyway 🙂 Thank You!

  22. Sir my Iphone 3g’s Wifi doesn’t work any more. Is there any chance i could get the iphonecake files and manually install them VIA IfunBox?

    • HI Arvin
      The best bet would be to reinstall the iPhone firmware and see if this fixes your wifi.
      If that doesn’t then the issue would be a hardware problem. Make sure you backup your data before doing this.

  23. when i install itools2012 it needs to be updated to 2013 but when i updated it an error occured and it closes the application… pls help sir 😀

    • HI Tamir
      Make sure you have a wifi or internet connection on your phone?
      I haven’t checked this process in a while so I am unsure if everything is still as it was.
      Good luck
