Dear ifixit, I followed your guide and instructions for replacing the battery on my iphone 4 and I did the replacement in just 10 minutes successfully. Thank you very much for the very clear and neat instructions. I am 71 years old and I assure you that so far I spent a lot on mobile repairs by technicians but from now on I can trust only myself and your technicians only. Once again thank you very much.
