First of all, check your phone's baseband (aka modem firmware) to see if you have 01.59.00. If you do, then it's possible to software unlock your phone. If you have a newer baseband, then you are out of luck at the moment as there is no software unlock solution for any newer basebands.

If you have 01.59.00, you'll need to jailbreak the phone, then use Ultrasn0w to software unlock it.

I would start reading the following links:

Whatever you do, do not update the iOS firmware on your phone as this will also update the modem firmware. There is a way to update the iOS version without updating the modem firmware. See this link:

Note that the current iOS version is 4.3 (the tutorial is old). But if you care about unlock, do not update the iOS version period!
