its not nice to hijack a thread.
if you have your 4.1 shsh blobs then follow this tutorial [HOW TO] Restore/Install firmware, No errors - SiNfuL iPhone
if you dont have your 4.1 shsh blobs you cannot go back to 4.1
if you dont know what shsh blobs are then you need to google it.
your question has been answered multiple times so just do some searching and you will find all the info you need.

I tried to use Itunes to restore and it does not allow, it keeps giving and error 3104 i tried to put into dfu mode and restore and it did it but cydia is still there i am not worried about saving any of the files or info just need it cleaned out any help would be great thanks.
why are you sending it to apple in the first place? what is the problem that is so severe that you need to send it in? is it a hardware issue?
anyway to help answer your question you should try using iReb. donwload it and run it, follow the instructions to get your device in pwned dfu mode then hit the UPDATE button not the restore button this will put the newest firmware on your device which is what is going to happen if you send it to apple.
