iPhone 4 Leads the Pack With Stunning Design, Interface
http://www.wired.com/reviews/product/pr_iphone_4
Apple’s fourth-generation iPhone makes its predecessors look like toys. Heck, even the iPad looks sissy now. It’s an impressive upgrade.
The defining feature of the iPhone 4 is its 960-by-640-pixel display, which has a pixel density of 326 pixels per inch, far higher than any other consumer display. Apps, websites, photos and videos look stellar. Text is crisper, images look rich and detailed, and colors are stunning. It’s been hard to put down this phone: Staring at that screen is addictive.
Currently, FaceTime is only available for iPhone 4 users, so the number of people you can video chat with is limited. However, Apple published FaceTime as an open protocol: Any software developer can integrate the service into their third-party software on Macs, Windows machines or even competing smartphones, such as the HTC Evo 4G.
However, AT&T’s overloaded 3G network remains a major concern for old-school telephoning. Call quality sounds clearer with a noise-canceling microphone on top of the handset, but reception problems persist

iPhone costs $188 to make
http://www.mobilecrunch.com/2010/06/28/iphone-costs-188-to-make/
Another day, another iSuppli teardown. The folks at iSuppli have found that the iPhone 4, according to their estimates, costs $188 to make. While this is almost comically low, it says something about Apple’s ability to mass produce phones and the high margins they’re able to make on relatively low-cost products.
In related news, iFixIt is now selling almost all the replacement parts you could want for your iPhone so you can build our own device at home, even further undercutting Apple’s dreaded hegemony.

Comments on iPhone 4 “antenna problem”:
Letter from Apple Regarding iPhone 4
http://www.apple.com/pr/library/2010/07/02appleletter.html
“We have discovered the cause of this dramatic drop in bars, and it is both simple and surprising.
Upon investigation, we were stunned to find that the formula we use to calculate how many bars of signal strength to display is totally wrong. “
Alan Arp says:
“Steve Jobs, shares displeasure with the critical coverage of the phone’s reception problems” Maybe if they acknowleged our concerns sooner the media storm wouldn’t have gotten so bad. I think people at Apple thought if they ignored the problem it would disappear. Obviously Apple is absolutely on its way to become the company they once hated.

Scenes from the iPhone 4 antenna press event (photos)
http://news.cnet.com/2300-1035_3-10004149.html?tag=mncol
Apple held an invite-only press conference to discuss its latest mobile device, the iPhone 4, and more specifically, the reported reception issues users were having.
Jobs referred to the situation as “Antennagate,” but said that getting signal loss from holding the iPhone 4 was “not unique” when compared to other smartphones.

Apple’s iPhone 4S Cracked Open, Money Spills Out
http://allthingsd.com/20111019/apples-iphone-4s-cracked-open-money-spills-out/
In the case of the iPhone 4S, Rassweiler estimates that the BOM cost ranges from $188 for the 16 gigabyte version of the iPhone 4S to $207 for the 32GB version and $245 for the 64GB version. Apple and its carrier partners sell the phones for $199, $299 and $399 respectively, typically with a two-year contract for wireless service that carriers use to subsidize the cost they pay Apple.

Nissan Scratch Shield iPhone case fixes its own scratches and blemishes
http://www.theverge.com/2012/1/16/2710969/nissan-scratch-shield-iphone-case-healing
A few years ago, Nissan developed a type of paint for its cars that can automatically fix scratches — now the company’s taking its tech off your car and onto your iPhone 4 or 4S.
And did we mention it heals itself? The case’s paint is made of polyrotaxane, which Nissan says reacts when its structure is changed and actually morphs back into its original shape, covering over the scratch. The process takes between an hour and a week depending on the severity of the blemish

iPhone to get 4.6-inch Retina display, report says
http://news.cnet.com/8301-13924_3-57402126-64/iphone-to-get-4.6-inch-retina-display-report-says
Waiting for an iPhone with a larger display? Hold on, Apple might already placing orders with suppliers, according to Reuters.
Apple is purportedly already placing orders with suppliers for a 4.6-inch iPhone Retina display, Reuters said today, citing a report in South Korea’s Maeil Business Newspaper. The phone is due in the second quarter, according to the report.
If accurate, that would be Apple’s third device with a Retina display. The others include the just-released 9.7-inch iPad and the 3.5-inch iPhone 4S.

Microsoft Passed On iPhone-Like Device In 1991
http://apple.slashdot.org/story/12/04/15/1246251/microsoft-passed-on-iphone-like-device-in-1991
Microsoft apparently could have been a contender in the smartphone market, instead of what WP7 is today. Former Microsoft CTO Nathan Myhrvold says he tried to convince Microsoft to make an iPhone-like device more than two decades ago.
‘The cost will not be very high,’ Myhrvold wrote in 1991.
How former Microsoft tech chief Nathan Myhrvold could have created the iPhone
http://www.geekwire.com/2012/how-nathan-myhrvold-almost-invented-the-iphone/
A cover story in Men’s Journal, called “How a Geek Grills a Burger,” casts the former Microsoft chief technology officer as a “mad scientist” living out a “nerd fantasy.”
“In 1991, Myhrvold predicted the emergence of the iPhone down to the smallest detail, describing a “digital wallet” that would consolidate all personal communication — telephone, schedule manager, notepad, contacts, and a library of music and books, all in one. It would record and archive everything you asked it to, he surmised. “The cost will not be very high,” he wrote. “It is pretty easy to imagine a $400 to $1,000 retail price.” Microsoft, however, was too cost conscious and risk averse to execute Myhrvold’s vision. “Hey, it was better than predicting the wrong thing,” Myhrvold says now.”

http://apple.slashdot.org/story/12/04/15/1246251/microsoft-passed-on-iphone-like-device-in-1991
Since cashing out of Microsoft, software genius Nathan Myhrvold has lived a nerd fantasy — digging up T. rexes, dabbling in Formula One, and creating a cooking bible only a mad scientist could love.

Leaked snaps said to confirm iPhone 5 speculation
http://www.reghardware.com/2012/05/30/iphone_5_rumours_confirmed_through_leaked_product_shots/
Much of the speculation surrounding Apple’s next iPhone appears to have been confirmed through allegedly leaked product shots which show the iPhone 5 to have a smaller dock connector, redesigned speaker grilles and a repositioned microphone on the rear.
Various images of the supposed next-gen iPhone were snagged by 9to5Mac, which reckons the images show the phone’s antenna moulded into a metal – or metal textured – backplate.
Further pics of the apparent iPhone 5 body show the front-facing camera repositioned in the centre, above the earpiece.

Why chip names tell us very little about the iPhone 5
http://www.zdnet.com/blog/hardware/why-chip-names-tell-us-very-little-about-the-iphone-5/20629
Summary: The problem with processor names is that history tells us that there’s very little we can deduce about the underlying hardware from these letters and numbers
Based on rumor and some guesswork, I expect that the iPhone 5 will feature a dual-core CPU, possibly clocked to 1 GHz, and an updated quad-core GPU powering the graphics. This should be more than enough of an upgrade to keep the iPhone ahead of the competition.

New iPhone prototypes have NFC chips and antenna
http://9to5mac.com/2012/06/25/new-iphone-prototypes-have-nfc-chips-and-antenna/
We have previously been able to pull data from PreEVT iPhone 5,1 and iPhone 5,2 prototypes codenamed “N41AP (5,1)” and “N42AP (5,2)”, which lead us to believe that the new iPhone will have a bigger 1,136-by-640 display. We also detailed a lot of the hardware (here), but we forgot one very important bit of information. Further investigation into this hardware code dump leads us to believe that these iPhones also have Near Field Communication controllers directly connected to the Power Management Unit.

Apple iDevice dock port to drive wireless streaming
Analog audio out, AirPlay in
http://www.reghardware.com/2012/09/03/apple_dock_connector_update_to_drive_wireless_streaming/
Will Apple’s new dock connector, expected to debut on the iPhone 5, signal the end of low-cost audio docks? The makers of such kit seem to think so.
With no analog lines in the new connector, there’ll be no simple port converter product either.
Ditching analog out will have not only helped Apple slim down the iDevice dock connector, but it will also drive speaker manufacturers and users toward wireless streaming using Apple’s own AirPlay tech, or over Bluetooth.

Six months under water and iPhone 4 STILL WORKS
http://www.reghardware.com/2012/10/11/six_months_in_lake_and_iphone_still_works/
In April 2012, though, Ken Hovanes accidentally lost his Apple hardware in Smith Lake, Alabama. Unable to see far into the murky depths, and seemingly unwilling to go for a blind diving expedition, Mr. Butterfingers gave up all hope and bought a new phone.
This weekend, however, the lake’s water levels were low enough to see part of the the bed, and Hovanes not only found his old phone, but managed to get it working again. Just about.
Apparently, after cleaning it up and drying it out, the phone turns on and the touchscreen still works. There’s no sound and the battery is kaput, but Hovanes is still overly impressed with the iPhone’s durability, sharing his story on t’interweb. If only it would connect to his computer.
Of course, we only have Hovanes’ word for the story, though his pics do do show an iffy backlight, a bulging battery and a cack-covered casing.

Replacing a dead iPhone battery
http://www.edn.com/electronics-blogs/brians-brain/4441295/Replacing-a-dead-iPhone-battery-?_mc=NL_EDN_EDT_EDN_weekly_20160128&cid=NL_EDN_EDT_EDN_weekly_20160128&elq=ec28ae117ab744f78dcc12fd385a63a0&elqCampaignId=26717&elqaid=30561&elqat=1&elqTrackId=76601df36ad24881a0641754e1f4b01b
This was my work (Verizon carrier, versus personal AT&T carrier) phone, and it was a Friday, so instead of switching to a different handset right away I ordered a replacement battery (complete with toolset) for $20 from Amazon with free Prime two-day shipping. It arrived mid-day the following Monday, and I set to work on the swap right away. Bafflingly, the battery-plus-tools didn’t come with any installation instructions; fortunately, iFixit came through once again. I recommend that you supplement this writeup with a perusal of their battery-replacement guide, which also includes additional images.
Removing (and replacing) the battery is relatively straightforward, thanks to iFixit and using the included plastic tool. The most challenging bit is not losing the pressure contact mentioned in iFixit’s instructions
Good news: when I got everything reassembled and turned the phone back on, it smoothly booted to full-on operation with a 75%-charged battery indication. Bad news: when I plugged it into a charger to top off the battery, it once again began rapidly discharging. I at least had sufficient new-battery power to get my stored photos off it, but it’s obviously reached a point of terminal demise; I suspect that the charging circuitry itself has failed.
