use latest redsnow then go to extras then check pwned dfu then follow instruction..

after that you can restore it to 4.1... if thres an error 3194...go to c\windows\system32\drivers\etc find the hosts and delete it then save , RESTART the PC then again used redsnow to pwned dfu then restore with iTunes..

Are you sure?
Is it working without saved backup with umbrella?

Apple is still signing 4.1 firmwares, there's no need for saved SHSH.

dont need pwnd mode, put dfu mode and restore it, error 1015, use kick recoery jailbreak and unlock it

hi!

use custom firmware 4.1

after using redsnow to put in pwned dfu mode,then in hosts file,you need to delete all lines terminated with apple.gs.then open ireb and just leave it open.open itunes and restore to 4.1
after that do ipad baseband 6.15,jailbreak and unlock

good luck
