There is a website called smacleo(dot)com Click on "cell phones" on the left and click on the iPhone 3G 16Gb and it offers "brand new factory unlocked iPhone 3g". It says it can use ANY Sim Card for ANY service provider. I'm wondering if it's real? I mean I got a old cell phone and I'm with sprint, so I was wondering if I could just put my SIM card in this "Factory Unlocked" iPhone 3g. Am I understaning that correctly? And Then I want to jailbreak it, which I kind of already know how to do because I'm typing this on a jailbroken iPod touch 1st gen.
