First of all -- I read the Upgrade Guide. My question isn't on there. I also searched for it. I don't want to annoy anyone with the same kind of post so I did try to search for an answer before asking. Thank you for reading. Scenario: Family Plan. Line 1: Old Nokia Phone with no data plan -- UPGRADE ELIGIBLE Line 2: iPhone 3GS -- Unlimited Data -- Not Upgrade Eligible If I go on Apple's website and try to purchase a current 3GS (just to see what will happen on pre-order day) I put in the option of "Replace a phone on my account with a new iPhone." Then I put in the upgrade eligible line's phone # and billing info, and social security. After that it asks me which data plan I want (since that upgrade eligible line doesn't currently have a data plan on it). What do I do at this point? Do I add a data plan and then call and cancel it after I get the phone? I realize I will just activate the iPhone 4 on iTunes with the line (Line 2) that I want the iPhone to be on, not the upgrade eligible line which I ordered it on, but Line 2 already has the unlimited data plan from my 3GS and I don't want a data plan on Line 1 (the one used to order the iPhone 4). So what do I do? Order it, add a data plan and then try to get AT&T to cancel that plan? THANK YOU!
