Yop.
It can be a problem with your SIM (Maybe you sim card is an old model).
You can try to restore your phone with iTunes (Remember to save your ECID before) to check that it's not a hardware problem.
I think it's just a problem with Ultrasn0w and a restore can fix the problem.

What's your Firmware ? 4.0 ? 4.01 ?
It's an old, or a new iBoot ? (Look this "How-to" to know your iBoot : http://www.iphonegen.fr/forums/viewtopic.php?pid=354196).

Use this to save your ECID : http://www.iphone3gsystem.fr/tutoriaux/ ... mac-linux/
ECID allows to restore your iPhone to 4.0 firmware.

But, I don't know how you can restore your phone without 4.0.2 Upgrade.

You should ask for a new sim card, it will probably work since other sim cards work too
You should also try to restore but you won't be able to jb your phone nor unlock it with ultrasnow because you can't restore to an "old" fw
