Iphone unlock blues

My lovely wife gave me an iphone for christmas in the hope that
we can hack into it and use on the cellphone network here colombia.
It almost worked, I spent 10 hours or so searching and researching
and I found the best set of instructions at Iclarified.

The instructions were good enough to get my phone jailbroken in
about 2 hours, not including the time that I kept searching the interwebs
for the last piece of the puzzle, how do I unlock the sim card in a new
iphone with the new bootloader 4.6?
(it was interesting that last week I couldn't understand what all
the iphone bulletin boards were saying, unlock, jailbreak, 1.1.2,
bootloader, now I feel ready to do open heart surgery on my cell
phone)

It appears that I can't. not yet. unless I buy all the equipment to edit
a simcard, it doesn't look like it will happen until the next version of
iphone software comes out. or maybe never. That's really a shame, because
the iphone without a phone is almost worth the money, I can surf the net
on wifi, zoom around on google earth, and apparently there are a lot
of games to download. The camera is almost as good as my previous
digital camera, and typing is a breeze compared with keying in "wassup"
on my cell phone.

If this thing worked as a phone I'd happy with it, the high cost would be
worth it as I zoom around through playlists and contact information.
Unfortunately, not yet, I'm stuck carrying my old ipod and my crappy
phone. Come on Steve Jobs, set my cell phone free.
