If it's like Sprint, there is no charge to activate one online, and no limit to how many times you can swap. We had a guy that every Friday afternoon would chat in to activate his "fun" phone (Pre), then on Monday morning would be back in to activate his "work" phone (Blackberry). That went on for about 4 months, until he got his Hero.
