Sn0wbreeze is for windows, it is the win32 version of pwnage tool which is OSX. If you do not have a computer to re-jailbreak from, then things will be difficult.
If you have things fixed and working and just need an FTPD account that is easy, just message me and I can get going on that. It is not a website though, you will need to use an FTP client, something like Filezilla or FTPrush on win32, Filezilla on linux, andFTP on ANDROiD, etc
