iFixit, the do-it-yourself tech company, has released an iPhone 4 repair manual. Their engineers worked 12-hour shifts for five days to create the repair manual for Apple's newest creation.

The iPhone 4 repair manual (http://www.ifixit.com/Guide/Device/iPhone_4) sports 10 guides, 122 images, and 181 bullet points. It shows you how to replace all the major components that may break or fail in your iPhone 4. W

"During our teardown, we investigated the repairability of the front and back glass panels," says the gang at iFixit. "It turns out that you'll be able to swap the back glass with little effort, but you won't be able to replace the front panel without also replacing the LCD. The LCD, glass panel, and digitizer come as one unit in the iPhone 4, and they are inseparable without damaging the LCD. We're going to keep investigating potential methods of separating the LCD from the rest of the front panel, but the outlook isn't good."

They don't have iPhone 4 parts in stock yet. But they're expected soon.
