My daughter has an iphone and as of yesterday her husband has a broken iphone.  They have two lines on their friends and family.  My husband and I have old (sim card) phones.  We also have two lines on our friends and family.  We want to cancel our friends and family and both get added onto to my daughter's.  This would add two lines to theirs.  Do they qualify for a discounted i phone?  And can the broken iphone number get transferred to the new iphone?   Since they are adding two lines, would they qualify for two iphone?
