Getting a device UDID from .mobileconfig

Question

I'm trying to write function similar to http://whatismyudid.com/ that, then approved, will return the users UDID and store it to a database for future reference with that user.

I have written a .mobileconfig xml doc that opens in the Profile Installer just fine but when I tell it to install the profile it responds with [alert] Invalid Profile but no alert body. No description, no code, no help.

I'm new to the mobile configuration game so any help would thrill me.

Here is my configuration file:

<?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://apps.mortlabs.com/device/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>MortLabs.com</string>
    <key>PayloadDisplayName</key>
    <string>Profile Service</string>
    <key>PayloadVersion</key>
    <integer>1</integer>
    <key>PayloadUUID</key>
    <string>B958E359-34C2-42F4-BD0C-C985E6D5376B</string>
    <key>PayloadIdentifier</key>
    <string>com.mortlabs.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>

The profile is initialized by navigating to http://apps.mortlabs.com/device/enroll.php with mobile safari

I found that by using the above that Apache was being talked to by the Ipad/Iphone - The post by Kyle2011 at https://discussions.apple.com/thread/3089948?start=0&tstart=0 filled in the rest of the solution.

Basically at the bottom of the retrieve.php page you need to redirect the browser to a directory by using a line similar to the following:-

header("Location: https://www.example.com/enrolment?params={$params}");

Where enrolment is a directory - this then calls the DirectoryIndex (typically index.php) which can then display stuff to your user.

To populate the $params variable you need the following line at the top of your retrieve.php script

$data = file_get_contents('php://input');

You can then parse the $data string to get what you need (try file_put_contents("data.txt", $data); or Kyle2011's example)

I also changed the Payload UDID to something different by using udidgen in a terminal on a Mac rather than just using whatismyudid.com's.

Update: From iOS 7.1 some of the files (the .plist IIRC) need to be served over https:// - they will fail to install if everything is served over http:// - probably best to serve everything including the .ipa over https:// to ensure future changes on Apple's side don't cause a problem.
