What's some good SIM Card editing software?

I finally got my hands on a SIM Card reader/writer. It's nice enough, simple, but the software it comes with is absolute crap. The point of getting the reader/writer was so I wouldn't have to unlock my AT&T phone to work with Cingular. (Yeah, that whole migration thing was seamless... right) Anyway, I know the software is out there, I just don't know where to find it.

Before I get the "that might be illegal", "you could f%$#up your SIM Card" lectures: I am well aware of the risks/legality of the situation. I am not "cloning" a phone number for illegal use, since it's my phone. I'm not too worried about the SIM Cards since I have two extra AT&T SIMs, neither of which are useful with the current IDs they have since Cingular just finished axing AT&T's network almost completely.

Is this of any use? I don't use it nor need it, but I noticed it just recently.

Close, but I dunno if it would work. My SIM Reader/Writer is a direct interface for the SIM card; this software is meant to go through the phone. I'll give it a shot though.
