That was removed because it does not work. Try searching for it in Cydia.

I believe they removed it because they are using Apple's files. Jailbreaking might be 'legal' now but that's still a no-no.
 
i will upload a movie later where i am recording with the iPhone 3GS

Not that I don't believe you, but can you prove that it's an iPhone 3GS and not an iPhone 4? Maybe take a video with a mirror or something?

Edit: Looks like even though the resolution is higher than default, it's not 720p. 1280x720 should take up nearly all of your screen (and the file itself says it's 975x548). Definitely interesting, I wonder why the phone would do that.

Edit 2: I'm an idiot, I didn't realize quicktime displays the resolution you scale it to when viewing it

OP why don't you just decrypt the firmware? Download the firmware to your Desktop and change the extension to ZIP and extract it. Then download VFDecrypt and unzip it to your Desktop. Once you've extracted the iPhone firmware files, locate the 018-7063-114.dmg and drag it to the Desktop. Now open up Terminal and type in, without quotes, "cd ~/Desktop" enter "./vfdecrypt -i 018-7063-114.dmg -o decrypted_fs.dmg -k 2ab6aea67470994ec3453791ac75f6497c081edd1991e560a61dd666ac4b73f43c781739". When done you should have the decrypted iPhone 4 4.1 filesystem in a dmg labeled decrypted_fs on your Desktop. At this point you can delete the other files you downloaded.
