I don’t usually dedicate much space here for jailbreaking news, but it’s a Saturday and news is slow. The Chronic dev team has released a new version of their GreenPois0n jailbreak for iOS 4.2.1. This is version RC6 for both Mac OS X and Windows.

No word yet on when the Linux version listed on their site will be released.

In addition to setting your iPhone 4, iPhone 3GS, iPad or later generation iPods free, this version will now also jailbreak the second generation Apple TV. This is an untethered jailbreak, meaning you can boot up your iOS device without being plugged into a computer.

Download and execute at your own risk.

Flaw in iOS allows lock code bypass

October 26th, 2010 at 10:30 AM No Comments Michael Stanclift

If the fact that the iPhone and other iOS devices are jailbroken by basically exploiting security flaws in Apple’s programming wasn’t enough to highlight Apple’s lack of security prowess, a Brazilian iPhone hacker by the name of Salomão Filho has found a new and much simpler flaw. This one is in Phone.app, and it allows anyone to bypass the security lock code on an iPhone to access the phone functions, thus allowing them to make calls and access contact information and voicemail.

And it can be done by just about anyone with thumbs, via Neowin:

To bypass any lock screen simply hit “emergency call”, then enter three pound signs, hit the green call button and immediately press the lock button and you will have bypassed the security feature on the iPhone.

According to Tipb this exploit has already been fixed in iOS 4.2 betas. It’s unknown if Apple will release a pre-4.2 update to correct this issue. For now the only known workaround is not to lose your phone. Good luck!

Thanks to @hasanahmad for the heads up.

TV Guide for March 30

This is the introduction post to the TechVirtuoso Guide, what we hope will become a daily breakdown of important IT tidbits from the previous day, and what we expect to happen that day.

Yet again, someone has come forward with another rumor that a CDMA iPhone is coming this summer. This time, it comes from the Wall Street Journal. The new iPhone would work on Verizon Wireless, as well as Sprint Nextel in the United States and a handful of carriers in other countries including South Korea and Japan. The current iPhone is designed to work on the vast majority of carriers world-wide, including AT&T and T-Mobile in the US, using a signaling technology called GSM.

It would seem that SSL isn’t as secure as once thought. The problem isn’t the encryption, but the certificate providers. Ars has a breakdown of how governments are working with the CAs to “subvert the entire system to allow them to spy on anyone they wish to keep tabs on.”

Apple has released a major update to OS X 10.6 “Snow Leopard” — fixes in version 10.6.3 include enhancements to USB, OpenGL, DNS, QuickTime X, AirPort, iCal, Mail, MobileMe, Time Machine, and numerous other areas of the operating system. Choose Software Update from the Apple menu to check for the latest Apple software via the Internet, including this update.

Future versions of the Ubuntu Linux operating system will change the way units are measured in the operating system and enforced throughout applications used in the OS. Starting in Ubuntu 10.10, coming this October, SI prefixes (base-10) will denote 1 kB as 1000 bytes, 1 MB as 1000 kB, 1 GB as 1000 MB, and so on. This is similar to the way OS X started measuring data in Snow Leopard. Neowin has a full breakdown of the measuring guidelines.

You will soon be able to jailbreak an iPhone over the air, instead of having it tethered to a computer. Your move Apple.

Need help running Linux as a guest OS in Microsoft Hyper-V? Sounds strange, but Microsoft has released a best practices guide to do just that. Download it off their website. Don’t blame us if you create a black hole in your datacenter though. In related news, Hypervizor.net has a great article on anti-virus exemptions in Hyper-V. Proper configuration of your antivirus can prevent performance issues, but also keep your VMs from being eaten alive by an aggressive scanning engine.
