It has now become clear that Apple doesn’t provide some new features intentionally in older devices, which could be turned on easily in a software update, just to boost the sale of newer devices. In iPad 2 Apple included “Mirroring” function which lets you watch the display of your device on a HD monitor or TV using Apple’s display adapters. But the said function is not available in iPod Touch 4 and iPhone 4. However, after following this simple guide you can easily enable HDMI video mirroring on your device.

If you are using iOS 4.3.4 or iOS 4.3.5, you can use Redsn0w 0.9.8 to get tethered jailbreak.
