I was told Minecraft PE will be updated on 23rd or 24th of may but in Australia it is the 25th and I know america is a day behind but how come it isn't updated yet?
From what I remember, the developer of PE said that once he got 0.3.0 out, he would try to release an update each month. If this is true, then we can expect 0.3.1/0.4.0 either in a few days, or 2 weeks at the most. The MC Wiki still says it's undecided though: http://www.minecraftwiki.net/wiki/Pocket_Edition_upcoming_features
I think early June, and should have creepers and furnaces for iron, those are garunteed but rumors say it has bows, pressure plates, and dispensers
The update is always one to three days after the Android version is upgraded (which sometimes is announced on Twitter), so of you hear about an Minecraft PE for Android update, expect it on iOS shortly after.
Today is June 30 and I'm still on 0.3.0 There's really no way that we can tell when the update will come. A few days ago, Daniel tweeted this "the only thing I can say is soon ..I think ". So hopefully, we'll have to wait at most another week.
