How to Enable HD Video Recording on iPhone 3GS (via Cydia)

The iPhone 3GS may not have a processor as good as the iPhone 4 but it itsn’t that bad either. It seems it is capable enough to record 720p HD videos. Some iPhone developers have found out a way to bypass the software limitation to allow this with an iPhone 3GS hack.

There are various ways of installing this iPhone 3GS hack and we will go with the easiest one which will also allow you to change recording resolution from your iPhone. This hack was created by Pierre-André Leclair.

Here’s a quick comparison of the video quality we are going to achieve as compared to the existing resolution on unmodified iPhone 3GS. Image courtesy Mike.


Since, this tweak is to be installed via cydia, you should have a jailbroken iPhone 3GS. Refer to following guides if not jailbroken already:

Here are the steps to Enable HD Video Recording on iPhone 3GS:

Go to Cydia > Manage > Sources > Edit > Add > and enter the repo address and tap on Add Source.



Once Cydia has finished downloading packages select Return to Cydia and then tap on Done.

Click on Official iPhoneBlogr repo and install both the app listed – Mobile Terminal iOS 4 & 3GS HD Video Recording.


After both apps are installed reboot your iPhone and open MobileTerminal.

Type su root

When prompted for password enter alpine unless you changed the default password yourself.

Now, type sh

Select the appropriate option from the displayed list. To disable HD Video Recording select (8) and to quit select (9)


Respring your device as prompted and you will now be able to record videos in HD on your iPhone 3GS. Let us know how you like this tweak for your iPhone.

    How do you do this? it doesn’t let me type the password, even though it has “password:” on the screen

    what password? I have no idea what you are talking about. please explain?

    After doing this I now have the problem that either loading up photos or camera results in both programs remaining in processes on the SB settings.
    I’ve tried disabling but to no effect, does anyone know how to restore settings through terminal?
    And yes, I’ve tried the disable option on terminal.

    just so you know, photos and camera are actually the same app. So its absolutely fine if you see two instances of it running.

    I did the hack but now I have jerky video, not fluid at all even if the image is better. How do I go back to original settings?

    Pierre you can refer to this post and uninstall this app:
    That will solve your problem.

    Repo doesn’t exist 🙁

    I got a iPhone 3GS,and as i try to download the above mentioned repo,it keeps telling me,”DID NOT FIND REPOSITORY”….
    The indicated repository could not be found,This could be because you are trying to add a legacy installer repository (these are not supported).Also,this interface is only capable of working woth exact repository URLs.
    Now what the heck was that?
    can someone explain…and how to do that again?
