How to find your UDID and Use a Beta Build

May 25th, 2009 by Ben Leave a reply »

What is UDID?
Every iPhone or iPod Touch contains a Unique Device Identifier (UDID), which is a sequence of 40 letters and numbers that are specific to that device. This is like a vehicle’s VIN number but much harder to guess. Here is an example: 2b6f0cc904d137be2e1730235f5664094b831186.

What can you do with a UDID?
The only way an iPhone can install programs is if Apple approves them. Applications in the App Store have been approved by Apple for general distribution, but beta/demo customers who wish to try the app before it is in the store need to register the UDID. This will allow the user to be approved for use of the application and embed a provision kit onto the phone. This kit will then grant permission so the application works on the device.

How do I get my UDID?

You can copy your UDID from iTunes. Here are the steps to getting your UDID.
Copy from iTunes
1. Launch iTunes and connect your iPhone.
2. In the left panel, locate the device and select it
3. This should reveal the device summary including its name, capacity, software version, serial number, and phone number.
4. To disclose the Identifier click on the Serial Number
5. Copy your device UDID (user ctrl c) from the Identifier text field in the Summary panel

Alternatively you can download a App called UDID that will email us your UDID

Once we email you the zip files with the bundle follow these instructions:

Step 1. Extract the files to a folder or desktop
Step 2. Open iTunes
Step 3. Click on the Applications Option in the Upper Left area under “Library”
Step 4. Drag over the .mobileprovision file into the right hand window for the Applications Library
Step 5. Ignore any warnings, if Any
Step 6. Drag over the folder .App folder into the Right Library window
Step 7. Sync your iPhone/iPod

Have fun!
