This is How Your Micro Sim Card Should Look Like Before You Put It Into Your 3G iPad
Alignment is your only worry, even if this means using tape on the backend to keep the card aligned properly if you over-cut your Sim Card.
[FYI: Got my Sim Card cut at Halo for 30.000 VND - the dude, Kevin did it incorrectly initially. The next day, I went in to fix it - he over-cut it, but I taped it in place with black electrical tape.]
