In anticipation of my EVO arriving tomorrow, I listed my iPhone 3g 16gb on ebay. I received a question through ebay asking for: Before I answer them, I thought I would ask here to find out why they wanted this information. Is it safe to give out? What is it used for? I assume they're wanting to know if it can be unlocked or jailbroken, but I really don't know anything about that. I've left my iphone at the 3.0 firmware because I had enabled the tethering option and didn't want to lose it with an update. Thanks for the help!
