I phone 5s is the bestest phone for me I have used this phone for last 1 and half year it have 16GB of internal storage cannot be expanded. As far as the cameras are concerned, the Apple iPhone 5s packs a 8-megapixel primary camera on the rear and a 1.2-megapixel front shooter for selfies. The Apple iPhone 5s runs iOS 7 and is powered by a 1570mAh non removable battery.it looks quite cool in my hand and give best impression on other about me . so it is soo cool to buy
