I updated my 2G iPhone to 3.0 last week. When this drops on Friday, I will be unlocking this phone for my wife and upgrading to the 3GS. Nice work from the dev team!
The work isn't that difficult. You have to shield components from heat then use a heat gun to heat the chip. The heat will soften the adhesive and melt the solder (The chip can take the heat if you don't over do it). Then it's just a matter of carefully removing the surface mounted chip.
A soldering iron isn't needed or used. The best and safest way to reinstall the chip is to clean up the board, then use resistive tweezers to solder one lead at a time. Working under a microscope, this isn't difficult, just tedious.
About 30 minutes for the whole job if done right.
I worked as a technician in a factory environment testing and repairing circuit boards built similarly. We usually turned this kind of job over to a rework tech that does nothing else all day.
@framitz: So a Vietnamese electronics pirate performed a hardware modification that is difficult to everyone except for NASA engineers? I'm still impressed...
I would imagine that not only is the chip strongly glued to the board but it is likely surface mounted and those contact points are tiny as hell. I'm not that bad with a soldering iron but I don't think I could de- and re-solder the chip without frying something.
But then again, I have no interest in the iPhone. ;)

I've done much more difficult jobs than this.
