I have been using this phone for quite sometime.Everything is great about this phone expect that it gets a little heated up with heavy usage.
But, it can be ignored because every inbuilt battery phones have this issue.Camera, Music player, etc. just works fine.
Build quality is amazing.The phone looks rock solid in hand.Another important thing which Apple should seriously think about is price.With so many chinese players in market today who are selling great features at a nominal price people might soon lose interest in expensive phones. Also there is a huge difference between prices depending on the memory storage.I think apple should definitely work towards bridging that gap. Otherwise will people will definitely lose interest in them because of high prices.
