I know this may sound strange and random, but after I finally was able to update my iPhone 4 with iOS5 my MacBook just up and died. It's totally unresponsive. I got a few messages saying "are you sure you want to shut down" over and over and now it won't turn on. The green light is on (power cord) but nothing else works. Just wondering if this could possibly have anything to do with the iOS 5 update. I have no idea how but it seems to be too coincidental. I also posted this in the iOS5 forum but no responses. I don't even know if it's possible that the two are related. Before I spend a bundle taking it to the Apple store for repair, I just want to be sure I am not missing something about trying to get it to start. Any advice or opinion appreciated. Thanks!!
