Some changes have been made in Sn0wbreeze v2.8b8, now it will verify IPSW files very quickly and believe me it’s really fast. Snowbreeze 2.8B8 will jailbreak all your iOS device and this jailbreak will be tethered, which means you’ll have to boot your iOS device in jailbroken state using iBooty every time you reboot.
If you don’t know about Sn0wbreeze it’s a custom (pre-jailbroken) firmware builder for Windows as Pwnage Tool is for Mac.
