• iPad 2 Teardown: Glass is 27 Percent Thinner

    // Gradly // Apple, blog, iPad, News, Reviews, Tech. No Responses

    iFixit has posted a detail teardown of the just released iPad 2, revealing a great deal about the inner working of the latest creation from Apple. The iPad 2′s glass is significantly thinner than the previous iPad. More from iFixit:

    • We did a quick glass and LCD thickness comparison:
      • iPad 1: lcd = 3.2 mm glass = .85 mm
      • iPad 2: lcd = 2.4 mm glass = .62 mm
    • The thickness of these components — especially that of the glass — could drastically reduce the durability of the device, especially the glass’ resistance to shattering. We’ll see in due time if the percentage of folks with broken iPad 2 front glass is dramatically different than that of the original iPad.
    • Lifting off the LCD exposes the iPad 2′s battery. We found a 3.8V, 25 watt-hour unit. That’s just a hair more than the original iPad’s 24.8 watt-hours, so any improved battery performance should be attributed to software and other hardware improvements.
    • We confirmed via software that the iPad 2 indeed has 512 MB of RAM.
    • The markings on the 1 GHz Apple A5 dual-core processor appear to be Samsung’s, but Chipworks will investigate in the forthcoming days to find out for sure.
    • Other components that power the iPad 2:
      • Toshiba TH58NVG7D2FLA89 16GB NAND Flash
      • Broadcom BCM5973KFBGH Microcontroller
      • Broadcom BCM5974 CKFBGH capacitative touchscreen controller
      • Texas Instruments CD3240B0 11AZ4JT touchscreen line driver
      • Broadcom BCM43291HKUBC Wi-Fi/Bluetooth/FM tuner combo chip
      • S6T2MLC N33C50V Power Management IC
      • ST Micro AGD8 2103 gyroscope
      • ST Micro LIS331DLH accelerometer
    • There’s also an Apple-branded 338S0940 A0BZ1101 SGP chip. This looks like the Cirrus audio codec Chipworks found in the Verizon iPhone, but they’ll have to get it off the board to make sure!

  • Untethered Jailbreak To Be Postponed Until Apple Releases iOS 4.3.1

    // Gradly // Apple, blog, Jailbreak, News, Rants & Raves, Rumors No Responses

    After the successful iOS 4.3 Untethered Jailbreak (video below), the hacker behind the exploit seemingly will hold his jailbreak until Apple releases iOS 4.3.1.

    With Apple already baking 4.3.1 the first one releasing an iOS 4.3 jailbreak will pretty much burn the exploit 😛

    Well Apple should release 4.3.1 very soon, because tomorrow everybody knows that @0xcharlie popped an iPhone 4 at #pwn2own through Safari.

    The hacker expected that Apple will release iOS 4.3.1 specially after the hackers (at Pwn2Own contest) has successfully hacked iPhone 4 via vulnerability which found in Mobile Safari running iOS 4.2.1.

  • Charlie Miller Wins Again by Hacking into iPhone 4

    // Gradly // Apple, blog, Funny, Jailbreak, News, Rants & Raves 1 Response

    After The French security firm Vupen hacked Safari in just a few seconds here comes a new winning story but this time hacking into iPhone 4.

    Charlie Miller kept his Pwn2Own winning streak intact with another successful hack of an Apple product. This time by successfully hacking into iPhone 4 using an exploit found in Mobile Safari to swipe the address book of the compromised iPhone.

     

    The attack simply required that the target iPhone surfs to a rigged web site.  On first attempt at the drive-by exploit, the iPhone browser crashed but once it was relaunched, Miller was able to hijack the entire address book.

    Miller said the attack works perfectly against an iPhone running iOS 4.2.1 but will fail against the newest iOS 4.3 update. Apple has quietly added ASLR (address space layout randomization) to iOS 4.3, a key mitigation that puts up an extra roadblock for hackers.

    In an interview with ZDNet, Miller said:

    If you update your iPhone today, the [MobileSafari] vulnerability is still there, but the exploit won’t work. I’d have to bypass DEP and ASLR for this exploit to work.

    As of 4.3, because of the new ASLR, it will be much harder.

  • iPhone 5 Design Images with Larger Edge-to-Edge Screen Leaked

    // Gradly // Apple, blog, Gadgets, News, Rants & Raves, Rumors 3 Responses

    We’ve just got claims showing an iPhone mold with a larger display and a thinner bezel, iDealsChina posted several “mold engineering drawings” for the fifth-generation iPhone.

    We just got what appears to be mold engineering drawings for iPhone 5. These would be used by case designers to create plastic, TPU, aluminum, silicone and leather cases. A while back we hear rumors that iPhone 5 would have a curved back but these images show iPhone 5 with the same form factor as iPhone 4 but with an edge to edge screen.

    Apparentely, The design looks pretty much like an iPhone 4 with the exception of a larger screen which seems to take up a larger portion of the front face. News that we previously heared by reports from Digitimes and the Wall Street Journal,

    Macrumers also said that:

    Chinese accessory manufacturers clearly get access to early design documents as has been evidenced multiple times. The early iPad 2 cases were indeed accurate representations of the iPad 2. iDealsChina was also the source of a design rendering of the 4th Generation iPod Nano which turned out to be an accurate depiction of the then-unreleased iPod Nano.

    Apple’s iPhone 5 will also sport a dual-core A5 processor, according to code in the latest iOS builds, in addition to enhanced voice control and iOS 5. The iPhone 5 is expected to be revealed at WWDC 2011 with a launch date in either June or July.
