My thought is a big fat "no."

It is possible to put open-source fimware on your device using a number of sites that are available on the fabulous WWW. When Apple introduces a powerful device like the touch or iPhone, there will always be people in the Web community looking to improve these products for the USER. Just to list some features that can be made available via unlocking: enable Flash capabilities for the Web(rather than simply HTML), install applications that are not limited to the iTunes store (3rd-party applications), customize the look of menus and displays. . . and much, much more.
In my opinion, Apple makes amazing products but places too many limitations on how they let you use the product
you purchased. When the teenage "hacker" found a way to allow the iPhone to be used on different carriers, it hit the media with a vengeance. The main reason was because AT&T no longer had sole rights to the iPhone. Apple combated this by sending an update that "bricked" the phone. Even though it was
not illegal to unlock the iPhone, Apple had every right to counteract.
There is a reason why T-Mobile is introducing the Android OS on phones for their network (See Adam's previous post on Android). T-Mobile seems to have a better understanding that consumers not only want to get what they pay for, but also be unrestricted when using the purchased product.
