iPhone FileType Mapping / UTI for ICS attachment in Mail

Hi Everyone,

I've been able to successfully map an application using UTI's from mail using my own file types such as .blah, .test etc, however I would like to create a UTI for the .ics (iCalendar meeting requests) extension.

I thought this would be rather simple, as I've been able to test reference to Word Documents, PDF's and others with no problem. But something seems different here.

Steps to replicate:
1. Start from a new window project (universal or otherwise)
2. Add the below xml to the info.plist file
3. Deploy to a device running something later than 3.2
4. Force Quit Mail or Restart iPhone
5. Open mail. Find an email with a .ics attachment.

If it is just an image that cannot be opened you're in the same situation as me, otherwise if it is surrounded by a grey border and gives you the option to open in your application then please share your secret (or configuration of xcode / ios).

<key>CFBundleDocumentTypes</key>
<array>
    <dict>
        <key>CFBundleTypeIconFiles</key>
        <array>
            <string>FileAttach.png</string>
        </array>
        <key>CFBundleTypeName</key>
        <string>ICS</string>
        <key>LSHandlerRank</key>
        <string>Alternate</string>
        <key>LSItemContentTypes</key>
        <array>
            <string>com.apple.ical.ics</string>
        </array>
    </dict>
</array>

If anyone is able to test this with a fresh project and report the results it would be greatly appreciated.

Does anyone know of a reason why this UTI reference would only work in some situations? Or know any of the mysteries that surround ics attachments?

Many Thanks,
GigabyteJack
