I recently began using your BYOP with an iPhone 3G I bought on eBay. I love the service and am looking forward to continuing. My question is this: If/when I upgrade to a newer model will I have to get yet another SIM, i.e. is my original SIM now locked to my present phone? I am in the market to upgrade to a 3GS but don't want to have to go through the hassle of paying for yet another SIM, waiting a week for it to show up, etc. Is it possible to simply move my original SIM to the new phone? If so, is there anything extra I need to do? If not, what are my options?
Thanks in advance for any help you could lend,
