iPhone3GS high-definition video recording hacked, can record 720P videos

We know that the Samsung S5PC100 processor used in the iPhone 3GS is capable of supporting 720P video recording. However, due to the camera only having 3 million pixels, and to conserve energy, Apple has restricted this feature, allowing only VGA resolution video recording. But today, foreign hacker Mike successfully unlocked the 720P video recording function on the 3GS, enabling video recording at a resolution of 1080x800 at 30fps. If you want this feature, follow the steps below, and you can easily have it too:

1. Upgrade your iPhone 3GS to iOS 4.1 and jailbreak it.

2. Install OpenSSH through Cydia and restart your iPhone.

3. Connect your iPhone 3GS to your computer while turning off iTunes.

4. Use WinSCP to log into the internal file structure of your iPhone 3GS.

5. Download the file HDVideo3GS.zip, unzip it to get four files.

6. Copy N88AP.plist to /System/Library/CoreServices/SpringBoard.app/

7. Copy the other files to /System/Library/PrivateFrameworks/Celestial.framework/N88/

8. Restart your iPhone 3GS to complete the unlocking of the 720P recording function.

The key points are steps five, six, and seven. You can use other methods to log into and access the internal file structure of your iPhone 3GS and copy the files inside. However, we kindly remind our readers: Apple must have limited this function after considering the overall hardware environment. Unlocking this function will cause some damage to the balance of the hardware environment, similar to CPU overclocking. While it brings powerful functions, it also results in energy consumption losses. Therefore, it's best to think carefully before proceeding with the unlock.
