Me and my wife are on family plan on AT&T. I upgraded to iPhone 4 on June of last year but my wife who is on the 2nd line chose to wait for the White iPhone 4. She still has the iPhone 3G. I checked our contract and mine shows to expire of June 2012 and hers says her contract expired? That's where I got confuse, we are on a family plan so why would hers shows contract expired? And then if my wife decides to buy the White iPhone 4 tomorrow, is our contract going to change? So instead of the contract expiring on June 2012, it will now be extended for another 2 years? I'm confused, I mean her line is just the 2nd line of our family plan, mine is the main line. I thought when you have a family plan, all lines has same contracts. Please advise, any help or suggestions will be greatly appreciated. Thanks.
