Hi folks, Last September I bought an iPhone 4 in the Netherlands. My provider offered to unlock it for free after the exclusivity arrangement ended. This fall I will move to the US. I would be happy to bring my phone and keep using it. In the Netherlands, getting a contract without a phone often entitles you to a discount (a "sim-only" plan), because they don't have to subsidize a handset. So far I haven't found a similar deal in the US. Would it simply be more profitable to buy a new US iPhone and sell the old one (or the new one, for that matter)? Note: I am not a frequent caller. I have a very hard time blowing the 150 monthly minutes in my current plan. As for data, I think I hardly ever surpass 200MB/month, and never ever surpass 500MB/month.
