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.

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

  2. 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.

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

  4. 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?

  5. 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?
