Which redsn0w are you using?

If that doesn't work set your host file to cydia, put phone in dfu mode and alt-restore in itunes (shift-restore Win)

You don't need to set hosts file to Cydia since Apple is still signing iOS 4.1, leave host file set to Apple and it still should work.
Use tiny umbrella as an easy way to switch servers.

Anyhow put phone in DFU mode and do an Option/Shift restore in iTunes and point to 4.1 IPSW. After a while you will get an error in iTunes and just use Tiny Umbrella to exit recovery. The phone should now boot to iOS 4.1 activation screen. If tiny umbrella does not kick it out of recovery, a second restore to 4.1 will resolve this.

tried that. itunes shows error 28

For error 28, you can try a different computer and/or usb cable, or removing the battery for an hour and retrying the restore; you may also have a hardware problem.
