SIM Unlock, I'm curious

[Wyrmbot]

Im sure there are information scattered across a gazillion topics, but I'm curious and thought it would be a good idea to gather the info in a central thread.

How are HTC phones generally locked?
Is it like a dongle or is it some obscure windows setting?

How someone can scatter some light on the subject.
Thanks.

Ps. I've ordered a HTC Touch Pro myself (locked).

Its done randomly.
Like for each IMEI each they make a random code. Its gotto be something with the programming part ie the software, since we have seen in the past people making programs that unlock these.
For the CODE part its just random , they make a lock and they have an unlock code for that IMEI.

Is there any way to tell if your Raphael is locked to a carrier except by inserting a diff sim? Everyone in my family has AT&T, so I can't do that. I'm assuming the AT&T Raphael is locked, but since it's only for testing you never know I guess.

The Fuze is locked I believe.. However, you can simply call Customer Care (611) and they will provide you with an unlock code.
