How to find iPhone/iPod/iPad UDID

The other day a friend of mine asked me how he could find the UDID for his new iPhone 4. Therefore I have decided to compile this quick How-To Guide.

The UDID number is a 40-digit sequence of letters and numbers, associated with every iPhone and iPod touch device, it is really easy to find if you know how to.


1. Connect your device with the USB cable. Start iTunes on Windows or Mac.

2. Select your iPhone/iPod under Devices menu, and open its Summary Tab.

Click for a larger version!

3. You will see the word ‘Serial Number’ there, click on it.


4. Upon clicking, the word serial number will change to ‘Identifier (UDID)’.

5. A 40-digit UDID appears, which you can copy to clipboard using command (Ctrl + C on Windows) and (Command + C on Mac).

Below find a video demonstrating what is explained above.


1 Million iPhones use T-Mobile.

This is interesting according to a T-Mobile spokesperson the #4 wireless carrier, which does not sell the popular Apple smartphone, is home to over one million iPhones. Most of the devices are older iPhone models, though a fair amount of customers have reportedly trimmed down their T-mobile SIM to fit in the microSIM slot of the iPhone 4.

Since T-Mobile does not offer the iPhone 4 and uses the AWS band for its 3G network, these iPhone models are unlocked and running on EDGE.

This guide is copied from iPhoneHacks, and we don’t take any credit for writing it.

Even though we have always been against Jailbreaking the iPhones, we took the plunge the other day after many frustrating hours with the iPhone 3G and IOS 4, and surprisingly enough the phone actually works much better now, which is why we have decided to add this How To Guide…..


Remember that this is not supported by Apple, and that if anything goes wrong they will not help you, and WE are not responsible for any bricked iPhones either.

having problems updating to iOS4???

When I decided it was time to update my iPhone 3G to the new iOS 4 little did I know that it would take me more than 2.5 hours, the only thing that kept me going was the fact that apparently many iPhone 3G users were experiencing. Other iPhone 3G owners are reporting updates that take hours and failed updates resulting in the sinister error 3002.

If you are in this situation however there seems to be some good news, there are ways to get around this problem by restoring your iPhone 3G instead of updating it. If your update is taking forever to complete, then the reason for this is that your iTunes is actually spending all this time creating a back-up of your phone. If you are in possession of a recent backup (which you really should be) then you can complete a full restore to factory settings, which will eliminate the need to back-up your iPhone and should result in a speedier update to iOS 4.

The same is true if you’re getting error code 3002. Just click on your iPhone 3G under iTunes and click the “Restore” button. After the restore, you may have to reinstall some of your apps, but it should allow you to run iOS 4 on your iPhone 3G without any other problems or lost data.

Word of warning however, if you are not sure whether you have a working back-up of your phone then don’t follow the above mentioned steps.
