12-core Mac Pro now available in Apple Store

The previously announced 12-core Mac Pro is now available in Apple's online store and retail outlets.Early Monday morning, Apple took down its online store. A few minutes later, the site popped back up listing 12-core option.Apple's new Mac Pro, which was unveiled at the end of July, is a beast of a machine. It features two 2.66GHz six-core Intel Xeon Westmere processors, 6GB of RAM, a 1TB hard drive, and an ATI Radeon HD 5770 graphics card. Its price starts at $4,999, but that figure could rise quickly, depending on the customer's needs.Configuration is one area where Apple's 12-core Mac Pro is especially impressive. Customers can update the processor from the 2.66GHz model to a 2.93GHz version. They can also include up to 32GB of RAM, add a RAID card, and install several more hard drives. Given the power of the system, it might also be a good idea to update the computer's graphics cards to the dual ATI Radeon HD 5770 option. For those who want a single card, the ATI Radeon HD 5870 is also available.Those looking to get their hands on a 12-core Mac Pro can order now and receive the computer in seven to 10 business days.

You can jailbreak iOS 6.1, but there are some catches

iOS 6.1 can be jailbroken via the program Redsn0w, but only in tethered mode and only for older iDevices.As detailed by the Microsoft-focused tech site Redmond Pie, Redsn0w version 0.9.15b3 can jailbreak Apple's latest OS. The jailbreak requires that your device be tethered, meaning you'll have to connect it to your computer each time you restart it.Further, the latest version of Redsn0w supports only older iDevices with an A4 chip or earlier. That means it'll work on devices like the iPhone 4, iPhone 3GS, and 4th-gen iPod Touch but not on the iPhone 5 or the latest iPads or Touches.However, an untethered jailbreak could kick off as soon as Super Bowl Sunday -- February 3 -- according to Redmond Pie. An iPhone Dev team known as evad3rs has been working on a full iOS 6.1 jailbreak.The new jailbreak would be untethered, so there'd be no need to connect your iDevice to a PC. And it would support a host of newer devices, including the iPhone 5, the 4th-generation iPad, the iPad Mini, the latest iPod Touch models, and even the latest Apple TVs.The evad3rs team has set up its own Twitter account and will likely offer up a tweet when the new jailbreak is ready for download.
