Piggback SIM

My 3G is currently unlocked with yellowsn0w, but I want to be able to upgrade it to 3.0 without waiting for a dev team unlock when 3.0 comes out, and I found this: http://www.********************/

They say the SIM will work on any FW and baseband, is this true? Has anyone ever used this site before?

That got filtered for a reason. It's a scam and is worthless.
