Here’s a shocker – you can actually enable HD video recording on the iPhone 3GS. Yes, you read that correctly. The ARM Cortex processor on iPhone 3GS is apparently capable of handling 720p video encoding, however, Apple has imposed some limitations in the software. With this hack, you can record video at 1080×800 @ 30fps at up to 20Mbps while the default settings for video recording on the iPhone 3GS are 640×480 @ 3Mbps. Here’s the how to:

1. Jailbreak your iPhone 3GS if you haven’t already.
2. Install OpenSSH via Cydia.
3. Reboot your iPhone 3GS.



4. Connect your iPhone 3GS to your computer, make sure iTunes is not running.
5. Download and install Cyberduck for Mac or WinSCP for Windows. Enter the following details to login to your iPhone:

Cyberduck

1. Download HDVideo3GS.zip file from here.
2. Navigate to /System/Library/CoreServices/SpringBoard.app/ directory and copy the N88AP.plist file in this location shown in the screenshot below.

4. Restart your iPhone 3GS and you are done!

If everything went well, you should now be able to record 720p video and here’s a demo video:

Well, reports have said that the iPhone 4′s browsing speed is better than the iPhone 3GS’s browsing speed. But how much better? Well, watch this video below for you to get a better idea for yourself:

So, as you can tell, the iPhone 4′s browsing speed is better than the iPhone 3GS’s, however, when the iPhone 4 was up against the iPhone 3G, the difference was a dramatic improvement. Another thing that helps the iPhone 4′s browsing speed is the Apple A4 processor along with 512 megabytes of RAM.

Want to compare the iPhone 4′s display to the iPhone 3GS’s display? Well, I have you covered thanks to MobileCrunch. Here’s a photo:

As you can tell, the iPhone 3GS’s display (on the right) isn’t as sharp and crisp as the iPhone 4′s display (on the left). The reason is, is because the iPhone 4′s display has a Retina Display and an IPS panel. The Retina Display allows the iPhone 4′s display to hold 4X more pixels than the iPhone 3GS’s display. As for the IPS panel, it allows the iPhone 4′s display to have wider viewing angles, just like the IPS panel in the iPad. For more info on the iPhone 4 and the Retina Display click here.

Well, Walmart has lowered the price of the 16GB iPhone 3GS to $97, which is very intriguing. So, does this mean that a 16GB iPhone 4G will cost $199 and will Apple offer the iPhone 3G for free? For you want-to-be iPhone owners, you should wait a couple of week to see if a new iPhone will be announced at the WWDC next month. Maybe this is Walmart trying to clear stock in time for the next generation iPhone, nevertheless, it’s still interesting that Walmart would do this. Then again, Walmart’s slogan is: Save money. Live better.
