Talked with apple: Hi, my name is Carlene R. Welcome to Apple! Good evening. How may I assist you today? Hey, I had a question about the iPhone and ordering one I'm happy to assist with that. How do you know if we're ready for an upgrade? Do you have us log into at&t and check for us before we preorder the phone And how does it work with the micro sim The process will be in place to verify your upgrade status. This is usually done with your account details such as phone number. What happens if I want to use another number's upgrade on the same account? At&t allows you to select a different number on a family plan, and use their upgrade on your own personal phone line Will the process apple has allow me to do this? For clarification on this I would recommend speaking with an AT&T agent as the process online only allows for your phone number information to be entered. And what about the micro sim This will arrive with the iPad to be activated with AT&T. I'm talking about the iPhone the new 4g Apologies for the mixup. The iPhone will arrive with a sim card for activation to be completed with AT&T. So if it arrives in the mail, I have to go to an at&t store to activate it? I cannot do it on my own? Once the iPhone 4 is available for purchase we will have full details on this process. But at this time this info is not available. Yes but I need to pre-order it on June 15 Yes this is correct and all information will be available then. Thank you.
