really helpful specially in doing the battery changes..so where is the best store to get the parts??
nice pictures...but do every one as to know about iphone? It's part of the enormous PR campaign for it. 90 % of the world do not care about too expensive and restricted products.
For everyone who has asked, Yes. I was able to put the iPhone 4 back together in perfect working order. Check out this picture that Jason Hiner took (with a second iPhone 4) of me holding the iPhone 4 that I disassembled: http://twitpic.com/21acdp
Very cool, appreciate you taking the time to do that and post it up. One note - you mention two mics, all past iphones had one mic and one speaker, is this design different?
This is absolutely an awesome article. I am going to add this to my "How-To" favorites. KUDOS to the author, and photographer!
I would have liked to see some close-ups of the individual chips as well as things like the 3-axis accelerometer, etc., instead of some of the redundant pictures. Also, a pointer would have helped explain some of the captions.
Interesting that the antenna assembly appears to be on the bottom, where your hand would cover it. Was it easy enough to get to the battery to be considered user replaceable? Also, I could not see the problems with holding it "wrong". Where was the dead zone creator spot on the Iphone? The little pressure connector that touched the back of the case, what band radio (wifi-bluetooth-?) was it for?
Did the phone work after re-assembly? From the look of things, it should be fairly simple to get it back together, as long as you don't crunch any of the connectors when you snap them all back in. Interesting hardware.
I was expecting this to be about some guy I don't know or care about buying an overpriced iPhone 4 and saying how great it is. But this was really "Cracking it open" and not just out of the box. I flipped through all the images and I was actually curious as to what the main components would be like, great article.
...but the other 10% appreciate devices and OS's that just work when you need them. Expensive? 3GS iPhones start @ $100. iPhone 4 starts @ $200. This is not expensive by any stretch of the imagination.
The whole point of this is that what we have tools that, just 20 or 30 years ago, would have been considered "magic" by just about anybody. It's not about how expensive or restricted it is... it's about how amazing it is!
Looks like the iphone battery will finally be something that an average person could easily replace.
Heard on the news that there's a req't to locate cell phone antennas as far from the brain as possible. If true, then explains why it's there.
Anything that is damp, or otherwise semi conductive can create the core of a capacitor which will readily conduct A/C waveforms such as RF. So, just putting any part of your skin surface on the metal band of the phone and particularly bridging the two metal segments can produce some coupling. The real issue is whether the created capacitive coupling is really that harmful to the antenna system. I've seen it make changes in the bar levels of shown on the display. But, since I don't know what those bars actually show, I can't accurately asses what kinds of effects are in play. Get a case for you iPhone and you'll be better off from a number of perspectives.
You better put that back together before your father gets home, or you going to be in big trouble! Mom
Very nice photos. It would also be nice to have some close-up pictures of the antenna's connections to the logic board, particularly at the top of the phone, in case this helps give someone ideas about hacking the antenna's wiring to see if it's possible to make the lower left gap less sensitive to being bridged by the user's hand (for people still resistant to just putting the phone into a protective case, which they should do anyway).
