Yesterday, I spoke with Apple and they confirmed that we CAN use this undocumented feature until they release a "documented" replacement. The real-time scanning version of iCandyMobile has been submitted for review but will most likely take up to 2 weeks to reach the App Store. We apologize for this, but we want to deliver the best product for you to use. We have been fighting this battle with Apple for months now and so we see this as a clear victory for apps like ours which absolutely require complete camera control.
So, stay tuned. We will update this page when the new app is up on the App Store.
