When I get my new iPhone tomorrow I was thinking of what to do with my current 3G. I don't want to sell it because I want to keep it as a back up. I never did any jailbreaking in the past, I only know what I read on the subject. So I am out of my element. Is there anyway I can use it for tethering and jail break it? would I need to have another account with AT&T or another mobile service to do that? Like I said, out of my element, why I am trying to keep it simple. I am just trying to make it useful outside of an Ipod touch, and other limited features. The reason I am keeping it is if anything happens to my new iPhone I have a back up. My buddy had a problem with his iPhone and was phone-less for 3 days. Which may not seem like much but when it's your work phone its pretty important.
