I found this article, and I've really been wanting an iPhone 4, but I do not want to be stuck with the troll that is AT&T. http://www.pcworld.com/article/202014/iphone_4_gets_unlocked_in_canada_for_a_price.html I had a few questions: 1. If i do this, will I be able to use the phone in the United States? 2. What carriers would this work with? 3. Is there any chance that my iPhone could brick if it detects that it is in the united states? Thanks. Also, any pricing information would be really nice.
