SpaceKitty, you've mentioned previously in this thread that for best results a restored iPhone 2G with a brand new SIM card should be used... I have the SIM card but the iPhone 2G I'm planning on using has not been restored because the owner still uses it (on T-Mobile). How important is it to restore the iPhone prior to activating? Essentially I want to use his iPhone but I don't want to inconvenience him by wiping it clean... what's my best option here?
I had assumed I could pop in my new SIM, plug into iTunes to activate, and once I'm done he could pop his T-Mobile SIM back in and be good to go. Do you have any thoughts that you'd care to share?
Thank you.
