I am clueless when it comes to jailbreaking and truthfully I don't want to go there. I made the stupid mistake of upgrading the 3G to 4.0 prior to getting my iPhone 4. Now I don't know what to do with it. I just had a bad experience trying to sell it through a company that shall remain nameless and I just got it back today. Any one have some good suggestions as to what I can/should do with this phone now?
