i have officially decided to drive one hour to my local apple store and buy an iPhone tommarow, but i have two questions, is my plan qualifying for an iphone? i am a current at&t customer, i am an additional line on a family plan of 4 phones. we have this plan "FamilyTalk Nation 700 Rollover & Unlimited Night/Weekend & Unlimited Mobile-To-Mobile Minutes" from when it used to be cingular. can an iphone data plan be added to this? i got my current phone a year ago. it has 200 sms text messages and insurance plans. when i activate my iphone (if i can), would these two things be replaced with the iphone data plan? or do i have to call to cancel insurance?
