Scenario: My parents and sis are in Los Angeles with a 213 area code with an AT&T family plan. None of them have a smartphone, but my dad is upgrading his eligible line into an iPhone 4. Actually, all 3 of their lines are eligible because their contract ended in March of this year and they just have been continuing to pay it (but only dad wants to upgrade at this time). I am currently residing in NY for the past 2 years, but have a 786 area code from my Miami days with my own individual AT&T iPhone plan. I am upgrading my eligible iPhone 3GS to an iPhone 4. So basically my parents would like me to join their family plan so we can save some money. They want to keep their own 213 Los Angeles area code at home, and I want to keep my current 786 Miami number because I have had it since 2007 when the first iPhone came out. But I have been living and using this number for the past two years that I have been in NY. How can we all end up on the same family plan, yet pre-order 2 iPhone 4's on Tuesday from Apple's website? Thanks!
