Okay so, I got the iPhone 3.0 GM seed from a friend of mine who is a developer a few days ago, and installed it on my iPhone. Here comes today, I get the new firmware (direct download from Apple, even though it's the same thing.. I'm weird like that) and restore it onto my phone. Now I'm completely screwed. Stuck on "Slide for Emergency", and no IMEI or ICCID is shown, and whenever it is plugged into iTunes, it gets stuck at "Waiting for iPhone..." for a few minutes, then "iTunes cannot activate your iPhone because he SIM card is not inserted or a SIM PIN is required." and restore needed is displayed on the iPhone. I've tried restoring this over and over.. and what I attempted to go into DFU mode and restore again (sleep + home for 10 seconds, hold down home, wait for iTunes to show up - says iPod and then switches to iPhone, tells me it is in recovery mode, iPhone screen is black) and I get the same thing. I'm so confused, is there anyone that could give me ideas? I've looked all over the forums and haven't seen anything like this..
