I recently purchased an iPhone 4 with water damage in the hope to fix it, but sadly due to the water being that of a swimming pool, and the detergents that are in the water, this tied with the iphone 4 not being rinsed with clean water right away etc, the corrosion started, and its not pretty. After the iPhone 4 went for a swim, it was then left completely assembled, and dried out, however as mentioned, the corrosion had already taken hold. Here's the photos of the damage. Once I had removed the Logic Board, i rinsed it in warm clean water for 10 minutes, and left to dry, then once dried out fully, I soaked the pcb for 3 hours in Isopropanol in a sealed container to losen up the corrosion so I could see the extent of the damage. This is what it looked like after the soak.. I then continued to clean up the area, and sockets seeing as the corrosion hadn't actually eroded the thin copper connectors away, so I thought I may actually try and get this thing back to life. I brushed gently, and treated the corroded area, removing all corrosion, and now, this is the state of the Logic Board below. Im just waiting on a new replacement battery to arrive, and then I will reassemble the iPhone 4, however, instead of me using the carcass from the original soaked iPhone 4, I have assembled another iphone 4 with new, and second hand parts which I purchased separately. New parts, White front glass with Retina lcd, home button switch/flexi, white back glass, new 5mp camera, white headphone jack, with volume buttons, and vibrate switch, and white dock connector. Proximity sensor, wifi board, power button, and new speaker/antenna also all replaced with new. Second hand parts for new build were just the iPhone 4 frame itself. Here's the logic board now as it stands, waiting for new batter to arrive so I can finish my rebuild. If after everything I have done, and it still don't work, its no biggy for me, I have enjoyed the experience of working on this. What shall I do with the rebuild white iphone 4 should it not work when rebuilt? I will sell it on eBay no doubt, and be honest in my description on what exactly I have done. I just thought some of you guys may of been interested in seeing these photos, hence me posting them here.
