i want to upgrade my phone.
i'll post this in both phones and plan because it has to do with both. right now i own a blackberry curve. i got in 2 years ago. i'm on the family unlimited plan. But, will i need to change my plan in anyway to get this phone? I don't know if sprint changed unlimited plans for 4g now, and i just want to know if my parents are going to have to pay MORE money for my plan to get this phonee
if so does how much and does that also happen for the Iphone 4S because i know that's still a 3g phone not 4g.(that's my back up phone)
please respond, and thank you!
