Samsung Galaxy S III uses identical Sony-made camera seen in iPhone 4S



12.06.01-Camera

iFixit in conjunction with chip analysts ChipWorks tore down Samsung's new Galaxy S III smartphone, revealing that the device is sourcing a newer version of the same Sony-made camera used in the iPhone 4S.

ChipWorks confirmed on Friday that the backside-illuminated sensor found in Samsung's new Galaxy S III handset is being sourced from Sony and may be a newer version of the component used in Apple's iPhone 4S. While iFixit initially claimed that the sensor is "basically the same unit" used in the iPhone 4S, further examination of the chip revealed that it could be a slightly refreshed product. It seems that the camera's sensor is where the similarities between the two devices end, however, as Samsung uses its own memory and optics to complete the unit.

ios_6_maps_iphone

9to5Mac’s source, who has access to the next-generation iPhone prototype, as well as data found out in a build of iOS 6 could report some more details about Apple’s next smartphone.

- Details in the iOS 6 beta indicate that the next-generation iPhone will run an application processor identified as S5L8950X that is still internally being referred to as part of the A5 family.  That processor initially showed up in iOS 5.1 betas alongside the S5L8945X that arrived in the form of the A5X in the current iPad.

Quick info about iOS 5.1.1 Untethered Jailbreak



musclenerd

MuscleNerd from the iPhone Dev-Team has posted some details on the upcoming untethered jailbreak from pod2g.

  • All info below is tentative and subject to last minute refinements
  • @pod2g's 5.1.1 jailbreak+untether is working out great. All devices are covered except for AppleTV3,1, which currently has no path for jailbreaking.
    - the initial 5.1.1 plan used a kernel exploit from @westbaer which unfortunately precluded use in iPod3,1 and iPhone2,1
    - @planetbeing stepped up and provided a kernel exploit that covers both of those. Those two JBers are the bomb!
  • The 5.1.1 A5 JB is very similar to the A5 5.0.1 JB. @pimskeks has done a tremendous job supporting both 5.0.1 and 5.1.1 in absinthe
  • Similar to 5.0.1, there will also be a 5.1.1 CLI "cinject" binary and redsn0w version of the 5.1.1 JB+untether. Absinthe, cinject, and redsn0w will all provide the same JB in different fashions.
    - timing is indeterminate. Plans are for this week, but a number of factors can influence that.
  • For those wishing to donate, we've set up a new 5.1.1 paypal URL: https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=4U6DQGJ2NRVUN
  • Please don't pirate AppStore apps (seriously, please do not).

‘New’ iPad 2,4 Uses 32nm A5 Instead Of 45nm A5 Found In iPad 2



46025-1

Anand Tech reported on a detail in the new iPad 2 model that many have overlooked. When Apple launched the iPad 3 with Retina display and A5X chip, the company also released the iPad 2,4 model, which is almost identical to the iPad 2. However in this model Apple replaced a 45nm A5 processor with a 32nm A5. This is the most efficient Apple’s processor and its 32nm die size is likely to be used in the next iPhone’s processor. The same 32nm A5 processor is used in the 1080P Apple TV, however it is limited to a single core.

RedSn0w updated to support iPhone 4S and iPad 2 on iOS 5.0.1



redsn0w-0910b7

The iPhone Dev-Team has updated RedSn0w to jailbreak the iPhone 4S and iPad 2 on iOS 5.0.1.

Version 0.9.10b7 of redsn0w adds a collection of useful features: It finally implements the corona-A5 jailbreak for iPhone4S and iPad2 devices still at 5.0.1. It can also re-install that jailbreak for those who accidentally uninstalled the untether. When stitching an IPSW, it can now grab your blobs directly from Cydia. It now shows a lot more info about your device (for instance, whether your iPhone3G has the vulnerable baseband boot loader, or whether your iPhone3GS has the old exploitable bootrom. (And the next new feature to be added will be built-in restore support, to provide an alternative to iTunes restores.)

Previously you needed to use Absinthe to jailbreak the iPhone 4S and iPad 2.

You can download the new version of RedSn0w from here.

We will update our tutorials soon.

Apple partner TSMC ramping up production of 28nm mobile chips



A5vsA5fromatv

Taiwan Semiconductor Manufacturing Company is expected to begin ramping up manufacturing of its 28-nanometer ARM processors.

TSMC is said to currently have a decent yield rate on its 28nm processes, but the company remains cautious on expansion, partially because the 28nm process is so new to the industry.

For example, Apple, one of the largest users of mobile processors, still relies on the 45nm manufacturing process for its latest-generation A5X ARM CPU found in the third-generation iPad. Apple is said to have viewed newer chips as a potential risk to their products, and have stuck with older processes to ensure availability and reliability.

Apple Testing A5X Variant in Next-Generation iPhone Prototype



features_hero

Apple is reportedly testing a prototype of next-generation iPhone hidden under the iPhone 4 casing. The next iPhone is said to not include the iPhone 4/4s form factor, and Apple is testing the prototype in older casing in order to throw off leaks. The prototype iPhone is used to test a variation of A5X processor in an iPhone. The A5X system-on-a-chip in the iPad 3 was specifically designed to run the new Retina Display, so that adding this chip in the next iPhone wouldn’t make much sense.

iH8sn0w have found a way to downgrade iPhone 4S and iPad 2 to iOS 5.0.1



downgrade-to-501

iH8sn0w, developer of sn0wbreeze and iFaith, has found a way to downgrade the firmware on A5 devices - iPhone 4S, iPad 2.

Using saved SHSH blobs, iH8sn0w was able to downgrade his A5 iPad 2 from iOS 5.1 to iOS 5.0.1. He says his method will also work with the A5X processor once firmware updates are released for the new iPad. That means that it's possible to restore to any firmware you want on A5 devices, as long as you have the SHSH blobs saved.

This is great news for those with the iPhone 4S and newer iPads. As it stands now, if you have to restore for any reason, you will be forced to upgrade to the latest firmware. This could leave you without the ability to jailbreak for some time.

Apple says new iPad operates 'well within our thermal specifications'



ipad_3_hand

On Tuesday Apple officially commented claims that the new iPad is running warmer that its predecessor.

"The new iPad delivers a stunning Retina display, A5X chip, support for 4G LTE plus 10 hours of battery life, all while operating well within our thermal specifications, Apple spokeswoman Trudy Miller said in a statement to The Loop. "If customers have any concerns, they should contact AppleCare."

Apple’s response came only couple hours after the publication of an infrared test that revealed the new iPad runs 10 degrees (Fahrenheit) hotter than the previous-generation iPad 2. The temperatures of the new iPad, however, remain well within Apple's specified operating temperature of 32 to 95 degrees Fahrenheit, or 0 to 35 degrees Celsius.

Thermal test of iPad's A5X chip shows operating temperature of 97 degrees



ipad

Yesterday we reported that the new iPad is running warmer that its predecessor. Repair Labs has conducted their own analysis and found that the A5X chip in the new device runs as much as 16 degrees Fahrenheit (about 9.5 degrees Celsius) warmer than the A5 chip in the iPad 2.

According to a series of tests conducted by Repair Labs, the A5X chip registered temperatures up to 36 degrees celsius (96.8 degrees Fahrenheit), compared to A5 readings of 27 degrees C (80.6 degrees F). The experiment involved opening up the tablets in order to directly measure the temperatures of the chips.

ipadheat

Left: New iPad, Right: iPad 2

Thermal imaging of the third-generation iPad and the iPad 2 demonstrates that the recently released iPad running 10 degrees (Fahrenheit) hotter than its predecessor.

Dutch site Tweakers.net performed the GLBenchmark test on the two generations of iPads for five minutes to measure a heat difference. Using an infrared camera, the publication discovered that the hottest part of the new iPad was 33.6 degrees Celsius (92.5 Fahrenheit), while the iPad 2 measured 28.3 degrees Celsius (83 Fahrenheit).
