When you put your iPhone 4 down on the dashboard of your boat, always remember to pick it back up and secure it somewhere before putting the hammer down. I failed to do this, and watched as my phone went flying toward the back of the boat to land flat on the deck - SMASH. iFixit to the rescue! (Sorry, no pics... the iPhone is my only camera)
I followed the 35 seemingly intimidating steps to replace the digitizer and glass without a hitch. Turns out, it's just time consuming and not terribly difficult. Be certain you use the right tools, though. There's no way I could have done it without the iFixit guide. The "view huge" picture options in the top left saved me a few times along the way.
Go slow. Follow the steps one by one, look at all the pictures closely. And, keep your SCREWS separated and labelled! There are a dozen or so screws that differ by only a few tenths of a millimeter! VERY easy for 43 year-old eyes to get mixed up when reassembling. I spent more time sorting screws than reassembling the phone. One other thing... the comments at the bottom of the step by step guides are well worth reading. Great community advice to be found there.
Seriously, I've been fixing gadgets and tech hardware since the 1980s. This is the first time I've used iFixit, but I'll definitely be back. Their great prices, excellent customer support and brilliant step by step guides are something I wish I'd discovered years ago. Super-fast shipping too! Customer for life.
