This is the best phone that I have used since I started using phones. The phone carries everything and meets all your requirements. The processor is great, which don’t let the phone hang, the camera is extremely good and is incomparable with any other phone.
The people usually says its has many restriction over downloading stuff from internet but I think we have to do some compromises for the security of our phone in order to avoid viruses. Though their are many software in app store to download songs from web to your phone. At last for the people who are planning to buy Iphone don’t think just buy it and have fun.
