I'm trying to activate my new iPhone 4. Synced it with iTunes and everything went well, but I still had "No service" at the top left. Rebooted, and got the "waiting for activation this may take some time" notification. Then I went to http://att.com/activations and went through all the steps. After the part where it asks for the last four digits of your SS, I got this error: ACT036: We are unable to process your transaction at this time. We apologize for the inconvenience. You may contact our Customer Care department at 1-800-331-0500 or dial 611 from your wireless phone. I might end up just bringing it to my ATT store, because I don't really want to call (IDK why) and they'll sync my contacts from my old phone. Just wondering if anyone has any other advice.
