I'm currently using a 16GB Black iPhone 3G on AT&T. I'm thinking of using QuickPwn to jailbreak my phone but I have one quick question. When firmware 2.1 is released, can I just plug my phone into iTunes and click on restore? I basically want to jailbreak my phone now but when firmware 2.1 is released, I want to install it as if my phone was never jailbroken. Your help is greatly appreciated. Thanks.
