iPhone 4 Unlocking Tool Now Available

The first iPhone 4 unlocking tool has been released. Version 1.0-1 of ultrasn0w provides iPhone 4, 3G and 3GS owners the ability to carrier unlock their iPhone to work across multiple providers.
While in some countries customers may be able to buy unlocked iPhones, most iPhones come locked to the specific mobile carrier. The process of "unlocking" the iPhone allows you to use the same phone across other GSM mobile phone carriers. In the U.S., however, options for alternative carriers are limited as T-Mobile is the only other GSM-based carrier and they do not even support the iPhone's 3G data network. In order to unlock your iPhone, you must first be Jailbroken.
Users should, of course, proceed at their own risk, as none of these procedures are sanctioned by Apple who warns that any issues caused by these procedures could violate your warranty.

(View all)But for us people who have to buy the iPhone 4 in another country and use it in a country where it isn't available, there is no other way but to unlock it!
A third party unlocking tool isn't necessary if your in a country like Australia where the carriers are required to unlock phones. Here you just call up your carrier and ask them to unlock it for you and they have to do it. Just did it today to get maximum dollars when I sell my 3GS.
That's awesome, I hope Europe follows sometime soon... But doesn't it then make the prices of subsidised devices much higher, since carriers can no longer rely on the fact that users will stay loyal to the given carrier?
I'll just pay cash again like last time.
While jailbreaking is legal, unlocking isn't...
Both Jailbreaking and Unlocking are legal (in the u.s.)

Can you get a micro sim from T-Mobile? Up until now, a T-Mobile user could just pop out her sim and put it into an unlocked iPhone, and Bob's your uncle. What would you need to do now?
cut the old SIM with scissors to uSIM size.
