Anyone else purchase this app and have it disappear from both your phone and iTunes? I bought it about a month ago, used it a little, then while thinking about adding it to another iPhone noticed it wasn't on my computer any longer. So I checked my original iPhone and it was no long there either. Checked the iTunes app store and NDrive is no longer found in a search. Looking at my account I see it was purchased on June 2nd for $4.99, so I don't think I'm crazy. So does Apple have an app "kill switch" and do they use it?
