gan mau nanya gan, jd ane pengen upgrade ios jadi 9.2.1 gan gara2 abis ganti sim card ke 4g. terus pas ane download & install tiba2 pertengahan download muncul tulisan "there is not enough available storage to download IOS 9.2.1. you can manage your storage in setting" padahal memory ane masih ada 1,3gb sedangkan kl ga salah kl mau upgrade ios 9.2.1 itu harus sisa 1gbkan gan, itukan kelebihan gan memorynya tp masih ga bisa.
