What is an Apple UDID? UDID is a serial number consists of 40 strings combined with letters and numbers which helps to identify every single iOS device includes iPhone, iPad and iPod Touch. This seems random code but in fact it's somehow related to the characteristic of the device hardware.
You can link all sorts of relevant data to the related devices with UDID. For instance, to link to the developer's account; to test and install apps before issue; for explorer to experience iOS beta. Apple connects Apple ID with UDID so that we can use iOS device to auto-download and install apps purchased from App Store, save music brought from iTunes, send push-up notifications and instant notice.
For the early application of iOS, the third-party developer and online advertiser applied UDID to collect users' data for associating addresses and recording apps using habit so that they  could push accurate ads. Many users was outraged by the Apple's invasion of privacy hence later on explorers were forbidden to apply UDID.

How to find UDD?

Method 1: Get UDID via iTunes
Connect iPhone to your PC and run iTunes. Click your device name on the left and the basic system information will show on the right. Keep clicking the serial number then you will see the UDID. Right copy then you can copy and send the UDID.

Method 2: UDID app
There are many UDID apps that you can check your UDID with. UDID+ is an easy-to use app from Emonster that you can get your UDID by just downloading and installing it in your device. There are two options - "Send UDID" and "Copy UDID", choose whatever approach you want and finish.

Hackers may get into your device and steal important information from you if your UDID is among the 1 million that AntiSec posted. So I suggest you to change your Apple ID passwords.
