Since some Boost Mobile phones use Sim cards, is there anyway to activate a phone that has Boost's $50 unlimited plan and use that sim in the iPhone 3G? I'm assuming you could just activate a plan with Boost, take the Sim card out of the phone, and insert it (along with a Rebel Unlocking Sim card) into the sim tray of the iPhone 3G and, you would get unlimited talk, text, & web. Do you think it's possible? I've tried google-ing it and nothing came up about it on the web. What are your thoughts?
