iPhone developer iH8sn0w has just pushed yet another update to Sn0wbreeze, bringing the version number up to 2.2.1. This new release fixes issues when jailbreaking Verizon iPhone 4 on iOS 4.2.6, adds drag and drop IPSW files support, 100% fixes the iBooks issue, and all the issues that you maybe experiencing when using Windows classic theme.

So as it turned out, the Verizon iPhone 4 is vulnerable to Limera1n bootrom based exploit, and untethered GreenPois0n kernel based exploit which makes it possible to jailbreak on iOS 4.2.6, untethered using GreenPois0n RC5.4.

With Verizon iPhones starting to arrive with lucky customers already, the question on all our lips was simple: is the CDMA version of Apple’s smartphone jailbreakable on iOS 4.2.6 using existing software? Well, it appears it is!

Moments ago, Apple seeded iOS 4.2.6 to public for Verizon’s CDMA iPhone 4 ahead of its launch date, that is February 10th, 2011.
