Wow, this was a funny thread to read. Wish I hadn't responded considering how old it was.
I at first was going to refute the OP about OTAs, but then as I read further on, I see he realizes he was mistaken.
Plus, NEVER take the word of the manufacturer completely at face value. I would instead look to what other people have to say. As someone else pointed out, the manufacturer is going to say things to keep you from unlocking the phone, even though they are providing you with a means to unlock it. Kind of stupid if you ask me.
