I am trying to setup the "Find my iPhone" application, but it's giving me the business! I am following the instructions on Apple's website to get my account rolling, but when i go to add a MobileMe account, i type my Apple ID in, and the password, and i get a "Device Not Supported - This iPhone is not qualified for free MobileMe service." message. I am running iOS 4.2.1, and i have a 3Gs. I know they have a strict 3-device limit, but i have not set this up on anything else! Anyone have any ideas? Thanks in advance!
