Hmmmmm I keep getting error 1013 and 21 while trying 2 jb after using snowbreeze! I already created a custom ipsw. Wonder whats wrong...
I was able to jailbreak successfully after several failed attempts. I kept on receiving error codes 3194 and 1013.
1) Get the latest version of snowbreeze, 2.7.1.
2) Download the 2.3.8 update file within iTunes and use this for your file in snowbreeze. The file will be saved in "C:\Users\XXXXXX\AppData\Roaming\Apple Computer\iTunes\iPhone Software Updates". XXXX is your profile on the computer.
3) I used tinyumbrella to save my SSHs and there is a reported issues involving tinyumbrella and jailbreaking 4.2.7 and 4.2.8. I had to go into advanced tab and unselect the box which says "Set hosts to Cydia on exit". Restart pc afterwards.
Step 3 may have been the reason why I couldn't jailbreak. After doing steps 1 -3, was able to jailbreak with no error messages.
