Folks who previously used the Camera+ iOS app might know that it was quickly pulled by Apple from the App Store when it was discovered that it featured a hidden function that allowed users to use the volume buttons to snap photos, which violated Apple’s terms. The app has since returned, sans the feature we mentioned. The funny thing is that an app called Quick Snap – Camera Plus has surfaced for $1.99 in the App Store and allows users to use the iPhone’s volume button as a shutter release. Did the folks over at Apple miss this app’s obvious feature, or is Apple relaxing some of the restrictions for the App Store?
