Assuming this is possible, I want to know if I should do it. The main thing here is the fact that it is running 3.0 and I haven't even gotten to use it yet because I had to sell my 3G on eBay to be able to buy the 3G S. I had my iPhone 3G Jailbroken and I backed it up Jailbroken. To my understanding this shouldn't be a problem cause iTunes wont backup the Jailbreak data, but I want to know what you guys think I should do when I get my new phone tomorrow.
