高考时买的iphone4用到大学毕业 上一年毕业买的6打算再干4年

老手机用了好几年了，够用就行，确实有需要再买。

coz是什么意思

It depends on how long it will work.

had a phone in canada, bought another one in korea, then got another in china. all because i forgot to unlock them when I leave the country.
now i can play 3 cellphone games at once....or read on one and play the other 2, or play 1 and read 2...or watever comination lolol

十四年间买过六个，别人不用了给我用的若干 算maniac吗
