Last evening iH8sn0w released a new version of the sn0wbreeze program with which you can make a jailbroken custom ipsw for iOS. Version 2.6.1 is entirely dedicated to owners of iPhone 4 CDMA terminals because it brings the possibility of untethered jailbreak on iOS 4.2.7. That version of iOS works only on iPhone 4 CDMA and on the GSM version we have already reached iOS 4.3.2 for which we already have other programs that do untethered jailbreak either through a custom ipsw or through a direct jailbreak.
iH8sn0w explains here all the details about sn0wbreeze 2.6.1, but nothing is specified about solving any bugs, so I assume it didn't solve anything. sn0wbreeze 2.6.1 is available here.
