Retrieve iPhone UDID on Safari
===

There is a great instruction for retrieving iPhone UDID on Safari.

http://www.bendytree.com/tips/Getting-an-iPhone-UDID-from-Mobile-Safari

I read this article carefully and follow it.

here is my script.

	<?xml version="1.0" encoding="UTF-8"?>
	<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
	<plist version="1.0">
	    <dict>
	        <key>PayloadContent</key>
	        <dict>
		        <key>URL</key>
		        <string>http://appfree.com/user/retrieve.php</string>
		        <key>DeviceAttributes</key>
		        <array>
			        <string>UDID</string>
			        <string>IMEI</string>
			        <string>ICCID</string>
			        <string>VERSION</string>
			        <string>PRODUCT</string>
		        </array>
	        </dict>
	        <key>PayloadOrganization</key>
	        <string>AppFree, Inc.</string>
	        <key>PayloadDisplayName</key>
	        <string>AppFree</string>
	        <key>PayloadVersion</key>
	        <integer>1</integer>
	        <key>PayloadUUID</key>
	        <string>9CF421B3-9853-4454-BC8A-982CBD3C907C</string>
	        <key>PayloadIdentifier</key>
	        <string>kr.co.gpon.profile-service</string>
	        <key>PayloadDescription</key>
	        <string>This temporary profile will be used to find and display your current device's UDID.</string>
	        <key>PayloadType</key>
	        <string>Profile Service</string>
	    </dict>
	</plist>


However, it still shows **Unsigned message** when the user tries to install the profile.

PS. Is there a alternative manual to work this issue?
