Just a few days ago, we posted a detailed step-by-step guide on how to enable HD video recording on iPhone 3GS. The entire process was – let’s just say – rather tedious. And I say tedious only because enabling HD video on 3GS now is as simple as installing a tweak.

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.
