i like ios7 system very much, i think optimizing system is very good,if running memory added to 2GB or 4GB,maybe the speed will same to 8GB OR 16GB Android system, the software will not really put off,but power saved well ,NO like android the back software running to waste power, so the iphone battery 1420mAH equal to samsung 2500 mAH battery,
WHY?
THE SHORT
