Iphone is great smartphone.
The way it is built the way it lands on your hand it truelly is a nice handset. Its weakest area is battery and memory.
I suggest you change your mind and buy yourself the blackberry leap. Blackberry leap is a modified blackberry z10.
The leap has a fatter batter 2800mah with two gigabytes memory process all those heavy apps plus the latest snapdragon processor to quickly access the internet and process just about every duty a computer needs to process. Buy blackberry leap it is loaded with latest blackberry is and is upgradeble to a higher os platform. All these for a lesser price and you will be doing everything an iphone user will be doing.
