Due to a bug in the recent iOS 4.2 update from Apple, iPhone 3GS phones may encounter an issue when trying to scan barcodes.
We have already submitted a fix to the App Store, and we are expecting the update to be approved within the next couple of days.
If you own an iPhone 3GS, please do not update to iOS 4.2 until this fix is released. If you have already updated to iOS 4.2 and are experiencing issues, hold tight! We are as frustrated as you are about the bug in the SDK, but when the update to Key Ring hits the issue will be resolved.
Again, this is only related to iPhone 3GS devices. Thanks for your patience, and stay tuned — we’ll update this post when the fix is approved by Apple.
