Unable to download and install iOS 6.1.2 update on iPhone 3GS
I received a software update notice to download and install iOS 6.1.2 update. I went to download update in General in Settings under Software Update. I then selected the button labeled "Download and Install." I agree to the license for the software, which then started to download. The download bar showed about 80% complete, would then stall until I received a message "Software Update Failed, An error occurred downloading iOS 6.1.2". What would caused a failure on an iPhone 3GS with iOS 6.1 installed already?
iPhone 3GS, iOS 6.1
