I can confirm another bug (as posted in the Nokia store app review wherein, selecting multiple contacts from the phonebook, the selected contacts (checked/ticked) gets deselected as I scroll to add some more - although the selection gets saved in the list.

Another thing, double entries (of contacts/numbers) are NOT prevented. I found this out when I tried to add contacts to my whitelist due to the bug above... Anyway, to filter out double entries?

Thanks, Matt!
