Hello, I am currently living in Costa Rica and I'm hoping to switch my Google Nexus One with an iPhone 4, but I really do not want an iPhone working through a jailbreak, I'm interested in factory unlocked so I can keep my iPhone 100% retail and clean. I was wondering if anyone has tried doing such thing? Is it a good idea? I have a friend who lives in Canada, I was hoping on asking her to buy it and send it to me. What do you think?
