Hello,
Have a look here at this forum page:

http://forums.epicgames.com/threads/...-no-iPad/page2

It talks about how we can only target a UDK game for the iPhone or iPod touch and not iPad. The solution it suggests is as follows:

__________________________________________________

<key>UIDeviceFamily</key>
<array>
<integer>2</integer> <------ edit there
</array>
<key>MinimumOSVersion</key>
<string>4.3</string>

You can edit "UDKGameOverrides.plist" and "Distro_UDKGameOverrides.plist"(you can find them at \UDK\UDKGame\Build\iPhone\);

__________________________________________________

However when I edit these two .plist files and RUN the frontend process, after 40% completion of the installation, the following error is displayed:

Start
..
..
..
blah!
blah!
..
..
... Install is 20% complete at phase 'InspectingPackage'
... Install is 30% complete at phase 'PreflightingApplication'
... Install is 40% complete at phase 'VerifyingApplication'
Install \ Update of "UDKGame-IPhone-Shipping.ipa" failed with Unknown error 0xE8000080 in 30.74 seconds
IPP ERROR: Failed to install IPA on device
[Apr 22, 2:45 PM] COMMANDLET 'iPhonePackager.exe deploy UDKGame Shipping' FAILED

Please help? I only wish to target my UDK game for the iPhone and iPod touch and NOT iPad. Please help?
