[title type=“h3″ class=“tfuse“]What is the UDID used for?[/title]
Every iPad, iPhone and iPod Touch device has what is called a Unique Device Identifer or UDID that assists with controlling what applications are installed on a device. Apple only allows for applications to be downloaded and installed through iTunes. To allow developers the ability to beta test apps, the developer can provide what’s known as an Ad-Hoc distribution to a user allowing the user to install an app without downloading the app through iTunes. In order for the developer to provide someone an Ad-Hoc distribution, they will need to create a Mobile Provisioning file that includes all the UDID’s of the devices that will be testing the app.

[title type=“h3″ class=“tfuse“]How to find your devices UDID[/title]
There are a few simple ways to locate your devices UDID. One is through iTunes which is only convenient if you have access to your computer. Another popular way is to download one of the many apps in the app store that do nothing more than open an email containing the devices UDID so that you can email it to someone. A simple search on some of these include: Ad Hoc, UDID Sender and UDIDit.

[title type=“h3″ class=“tfuse“]What is Ad Hoc Distribution?[/title]

Ad Hoc Distribution allows you to try an application before it’s available in the iTunes App Store. This is how we distribute iPhone applications to beta customers.

These instructions assume you have a .zip file. You can also look at instructions for .ipa files.

Developers, if you have any customers running Windows Vista, you’re better off distributing with an .ipa file, so that iTunes handles the unzipping. To create a .ipa, move your AppName.app directory into a new directory called Payload, then zip the Payload folder and change the file extension to .ipa.

[title type=“h3″ class=“tfuse“]What You’ll Need[/title]

Before beginning the installation process you’ll need:

[check_list]

• The .zip file for the application (usually AppName.app.AdHoc.zip)
• The .mobileprovision file for the application (usually Ad_Hoc_Distribution_Profile.mobileprovision)
• Your Device: the iPhone or iPod Touch whose UDID you emailed us previously (Remember?)
• The computer you normally sync with your Device
• We usually send the .zip and .mobileprovision files to you via email.

[/check_list]

[title type=“h3″ class=“tfuse“]Installing the Application – Windows XP[/title]

[row_box class=“border box_white box“][dropcap1]1.[/dropcap1] If you have the .zip (.ipa) and .mobileprovision files in an email, save them to a convenient location, such as your Desktop.[/row_box]
[clearboth][divider type=“space“]

[row_box class=“border box_white box“][dropcap1]2.[/dropcap1] Drag-and-drop the .mobileprovision file onto Library → Applications in iTunes. On the Mac, you can just drag it to the iTunes icon in your dock.
Extract the .zip file. To do this, right-click the .zip file and select Extract All… . Step through the wizard and accept the defaults by clicking Next.
[/row_box]
[clearboth][divider type=“space“]

[box type=“warning_box“ class=“border box_pink box“]WINDOWS VISTA USERS: The built-in “Extract All…” command corrupts the application so that it cannot be installed. You should try using a different zip program like WinZip or WinRar to extract the Zip file. Better yet, ask the application developer to send you the application as a .ipa file instead of a .zip file, then you don’t have to unzip it. [/box]

[row_box class=“border box_white box“][dropcap1]3.[/dropcap1]
Find the .app folder (usually AppName.app).

[row_box class=“border box_white box“][dropcap1]2.[/dropcap1]
Drag-and-drop the whole .app folder onto Library → Applications in iTunes. On the Mac, you can just drag it onto the iTunes icon in the dock.
