By Unlock, I mean being able to use it with another phone company, by changing the sim card. Please, don't tell me to use search, I did and only found people who where looking for a tut. I'd also wanna know, how do you do to buy it? Can you buy it without a sim card, or you gotta got to pay the 3 years (I'm in canada) and after remove the sim card. If I gotta pay for the 3 years, it will cost way too much.
