It's pretty easy to take your cell phone number from one carrier to the next, but a lot of people don't. Why? Generally you have to buy a new phone from your new carrier, right? Wrong. Popular Science has an article online on how to unlock your cellphone and reprogram it to your new carriers ID. Pretty common overseas, but unheard of in the States. Using this same principle, you could buy a muy fancy Euro/Asian phone and program it to work in the US. Cool!
