iClarified performed several boot time tests for iPad 1, iPad 2 and iPad 3 on the latest iOS 5.1.

The video is synced on the down click of the power button. Take a look at the results:

Surprisingly, the boot time has got slightly slower over each generation. Not a big deal though, since users don't reboot iPad that much anyway.

UPDATE: Apple released iOS 5.1.1 and has stopped signing iOS 5.1, so you can NOT restore to 5.1 any more (both original and custom), unless you have saved your SHSH keys for 5.0.1. If you are on 5.1 you can jailbreak with redsn0w. iOS is also tethered jailbreakable with redsn0w.

This is step-by-step instructions on how to perform tethered jailbreak of your iPad 1 on iOS 5.1 firmware using RedSn0w 0.9.10 for Windows.

Tethered jailbreak means that each time you restart your device you will need to connect it to a computer and run redsn0w.

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.

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.

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.

When the original iPad was released, there weren’t many apps available for the device. So Apple allowed apps developed for the iPhone’s smaller display to run on the iPad by using emulation. The apps could use only a fraction of the iPad’s display. Alternatively, iPhone-specific apps could be run in a 2x mode, utilizing pixel doubling technique to fill the iPad’s display. However, in 2x mode text and artwork look pixilated and blocky.

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.

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).

During the early Monday call, which outlined a surprise stock dividend and buyback plan for the company's $100 billion cash horde, Cook said that "[Apple] had a record weekend and we're thrilled with it." Apple also announced yesterday that it has sold 3 million new iPads in less the four days of availability.

It should be noted, however, that pre-ordered items are commonly not counted as sales until a transaction is complete and thus those iPads that are awaiting shipment were most likely not part of the final tally.

“The new iPad is a blockbuster with three million sold―the strongest iPad launch yet,” said Philip Schiller, Apple’s senior vice president of Worldwide Marketing. “Customers are loving the incredible new features of iPad, including the stunning Retina display, and we can't wait to get it into the hands of even more customers around the world this Friday.”

According to The Wall Street Journal, Sharp Corporation is still doing its best to start ramp up production of Retina displays for the new iPad. The company is expected to start shipments in the nearest feature.

The panels are to be used in Apple Inc.'s new iPad, according to people familiar the matter. The first batch of the U.S. company's newest tablet, released Friday, were not equipped with Sharp's LCD panels after the Japanese company faced difficulty in customizing the screens according to Apple's requirements, one of the people said last week.

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:

Following the iFixit’s dismantiling of an iPad 3, Chipworks has started sharing the results of its own new iPad teardown. The most interesting discovery is that Apple has seemingly reused cameras from its prior devices for both the rear and front cameras of the iPad 3. The rear camera that is shown above seems to be the 5 MP CMOS Image Sensor the company used in the iPhone 4.
