Flappy Bird is Gone?
I'm sure that most people don't care about this and some may have already realized this is possible, but I just realized I could still download Flappy Bird from the purchased app section on the app store.
I didn't like the app and deleted it after having it on my phone for a day -- I also didn't sync my phone in that time, giving me a backup of the app.
Just now I was looking for an old app I had purchased and realized that Flappy Bird was still available for me to re-download from the store, even though it's been pulled. I don't know how long it takes for Apple to entirely remove an app from circulation but apparently it's longer than you'd think.
So if you got Flappy Birds, deleted it and regret that -- there is hope. even if it's only until Apple gets wind of this.
