in the past two days, we have received notices from you that apple has been rejecting some apps due to some undocumented API's.
today, openfeint issued a fix and a workaround for the rejections.
we are on top of it and we will update the corona sdk as soon as possible.
as usual, the fixes will be rolled into daily builds and we may have the fix in for today's 11/11 build.
