A5X Chip Floorplan Reveals Significant Space Required for Quad-Core Graphics
Thanks to various teardowns, we already know that the A5X system-on-a-chip is being manufactured by Samsung and is using the same 45-nm process used for the A5 package in earlier devices. Having stripped down the new iPad, UBM TechInsights found that the amount of area taken up by the quad-core graphics found in the A5X, a significant boost from the dual-core graphics found in the A5.
What should be noted is that the processor cores from ARM are identical in look but the extra real estate on the processors (the A5 measures at approx. 120 mm^2 vs. the A5X which measures at 163 mm^2) is accounted for by the the PowerVR SGX543MP4 GPU cores, of which they are paired in groups of two and then symmetrically opposed to each other.

Slimmer 13-Inch and 15-Inch MacBook Pros Reportedly in Production
Digitimes now reports that Apple has already started production of slimmer models of the 13-inch and 15-inch MacBook Pro. As the report claims, the MacBook Pro line will remain distinct from the MacBook Air line; of course, the first ones will remain more advanced, but will reportedly lose their optical drivers.
The MacBook Pro will no longer have an optical drive enabling thinner designs, the sources indicated. Despite the slim profile, the new devices will feature more advanced specs than the MacBook Air in terms of CPU performance and storage capacity, the sources said.
I0n1c Performs Untethered Jailbreak of the iPad 3 [Video]
Stefan Esser, better known as i0n1c, just announced that he has successfully performed an untethered jailbreak of the iPad 3.
Okay my iPad3,3 is now untethered jailbroken...
Although the iPhone Dev-Team already announced their own jailbreak of the device earlier today, they did not specify whether their jailbreak was tethered or untethered.
I0n1c's jailbreak will likely work on all iOS 5.1 devices including the iPhone 4S if its released. Earlier this week he posted images of a jailbroken iPad 2 on iOS 5.1.
UPDATE: I0n1c posted a YouTube video to show the jailbreak:

The rear camera that is shown above seems to be the 5 MP CMOS Image Sensor the company used in the iPhone 4.
