iPhone 4S logic board replacement
I purchased another iPhone 4S, removed the logic board and replaced it with the one from my damaged phone. The damaged phone was 32gb and the replacement model was only 16gb. I figured this wouldn't matter as the memory is attached to the logic board itself so as this was being removed I bought the cheapest replacement available. The repair is fairly straight forward and is much easier than replacing the glass screen which I've had to do on a number of occasions for friends. There are many links on YouTube which are perfect to follow. I have subsequently purchased iCloud data to avoid the worry of something like this happening again. I think I was fortunate to have not damaged the logic board otherwise this repair/replacement wouldn't have been possible.
