Well I hate to tell you guys but quite simply your mistake was using Sn0wbreeze. lets just say it's not the best jb program out there! just stick with the Dev-team Geohotz and maybe Comex.
This is the correct answer. Although I thoroughly agree with labman's assessment of sn0wbreeze, creating a new unhacktivated ipsw with sn0wbreeze will probably work for you.
