iOS 6 and Factory Reset

[Macnificant]

I sold my iphone 4s have a beta version of iOS 6 on it and I am trying to restore to factory setting to mail it but I am getting an error stating there is an error in downloading software for the iPhone.

Can anyone help me out?

You need to put the phone in DFU mode first:

After that it will restore fine.
