This is Kinda Un-related To RCs…. but then again… I reckon many RC Owners have IPhone 3GS, and if you do a little “hack” that enables you to record in HD, you can now leave your FLIP TV or your Creative VADO back home and give your pockets more space for a Engine Thermometer or a tuning instrument… I just did this on mine.. I thought it didn’t work at first, but when I checked… OH FUCK! resolution up from 640 x 480 to 1080 x 800!

Get the needed HDVideo3GS-rev2.zip here!

*UPDATE* Many users have reported that performing this tweak has caused their camera to become sluggish in low-light situations and they are unable to playback the HD videos on the device itself. This seems to be because of the 1080×800 resolution. I have updated the download link with files that will set a 960×720 resolution which seems to fix this problem. Hopefully a new update will be released soon that will allow a higher resolution without slowing the camera down. Also, there should be an SBSettings toggle out soon for this. Otherwise you can download the original files here. Just install them using the same method you used to install the mod to get your device back to normal.

The ARM Cortex processor on iPhone 3GS is apparently capable of handling 720p video encoding, it is just that Apple has imposed some limitation in the software which Mike has successfully managed to bypass to allow video recording at 960×720 @ 30fps at up to 20Mbps. The default settings for video recording on iPhone 3GS are: 640×480 @ 3Mbps.

The tutorial below will show you a very simple way to enable HD Video recording on your 3Gs. It is as simple as replacing 4 files via SSH.

STEP 1: Jailbreak your iPhone 3GS (if you haven’t yet) using the instructions posted here to jailbreak your iPhone 3GS on iOS 4.1 using Limera1n or GreenPois0n.

STEP 2: Install OpenSSH by opening Cydia, tap on the Search button and write down OpenSSH then install this app and reboot your device.

STEP 3: Connect your iPhone 3GS into your computer via USB and make sure that iTunes is not running.

STEP 4: Download and install Cyberduck (Mac) or WinSCP (Windows) to SHH into your device and enter the following login information to get into your iPhone:

  • Hostname: The IP address of your iPhone/iPad/iPod touch. Setting –> WiFi –> “Your Network Name
  • User name: root
  • Password: alpine
  • Protocol: SFTP in case you running Mac or SCP for Windows.

Here is a video tutorial on how to do it in case you’re lost:

STEP 5: Download the pre-edited file HDVideo3GS.zip.

STEP 6: Now copy N88AP.plist file to /System/Library/CoreServices/SpringBoard.app/

STEP 7: Now copy the other 3 ,plist files to /System/Library/PrivateFrameworks/Celestial.framework/N88/

STEP 8: Almost finished! Now simply reboot your device and enjoy the trick!
