How to Check ECID

 

Apple has added a new security system called ECID. ECID stands for Exclusive Chip ID. iPhone 3GS, iPod Touch 3G, iPod Touch 2G MC and almost every upcoming iDevice is affected by this security. ECID is a unique chip id for all devices.

When you restore your iPhone, iPad, iPod Touch, the iTunes contact Apple servers and generate signatures for your device. If you want to secure your future jailbreak, it’s important to save these signatures before a new firmware comes out. Because once the new firmware is out, Apple stops signing older firmware and without a signature for older firmware, you cannot restore your iPhone, iPad, iTouch to that older firmware. Apple won’t let you downgrade your firmware. But if you have signatures saved for an older firmware for your device, Apple won’t be able to stop you from downgrading firmware even if they stop signing older firmware.

In this guide you’ll learn how to save your iPhone, iPad, iPod Touch ECID in both Windows and Mac operating systems.
