Yes you read that right! As the title suggests, you can now enable HD video recording on your jailbroken iPhone 3GS, running iOS 4.x. 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 1080×800 @ 30fps at up to 20Mbps. The default settings for video recording on iPhone 3GS are: 640×480 @ 3Mbps.
Simply follow the instructions posted below to get it working on your iPhone 3GS. I have tried it on my iPhone 3GS (jailbroken using Limera1n on iOS 4.1) and it has worked perfectly !
