Is it possible to detect whether a user reviewed my game?

Hi,

is there a Unity method or a plugin that could return me whether the player gave my app a review and possibly also return what rating (how many stars) he gave the app?

i.e. for maybe doing sth like:
if (notRated PopupNotShownSince(n days)) {
ShowPleaseReviewPopup();
}
else {
ShowThanksForReviewingPopup();
GrantSomeBonus();
or: UnlockHiddenLevels()
}

sorry for the bump, but I’d reeeeally like to have this feature;
has really noone stubled upon this?

no there is no unity method and plugins cant do it either, since appstore does not currently share that type information for privacy reasons (at least that was the case year ago when asked at apples dev forums)
