hi. i was recently approved for financing for the iphone 5s 64gb 0% interest if paid in full for 12 months. i really want a new phone because i have a need for packet data because my gamily lives in another country and calling them is crazy expensive. i have an ipod touch 32gb 5th gen for a year now. i am not entirely sure whether i should sell it off or keep it? i need to make sure that the 5s wont die out on me because i chat for 2-3 hours continuously. please help. because i feel that if i get the 5s and i have the ipod touch 5 it will be kind of redundant. and if i do decide to purchase the iphone 5s (unlocked), will it be worth it serving as my first ever iphone? Thanks in advance!
