Last year, my wife's iPhone had an issue with the microphone. Apple replaced it under warranty, but only a few months later the refurbished model failed and started kicking back a 2001 error. I made a genius bar appointment and it's safe to say that my experience was less than great. I've tried a number of times to bring it back to life, but no go. It would always fail to restore. Flash forward. Today I plug it into my Mac (same Mac used in the past) figuring maybe iOS 6.1.3 might have some magic in it. Once it got a charge, I got a message about a passcode. My ears perked up, since my personal iPhone doesn't have that. Sure enough, the iPhone 4 had come back to life. All the data still in tact and working without an issue. Never updated and it's completely functional. How's that for odd.
