This is a great phone, I have it a month now and it is almost a part of my life now. I love it, plenty of space for songs and apps. Although I did not get it off Amazon I have it on contract.
Camera: The Camera is very good, both front and back, it works well for Skype and FaceTime. the focus is very good and pictures and video are very crisp and clear, for example I took a picture of Lough Island Reavy, Ulster, Ireland, and now use it as my Lock Screen.
App Store: There is literally an UNLIMITED supply of apps you can install for free, not much more to say about it.
Design: There are some design flaws that knocked it down a star, for example people who have it are complaining that the screen cracks so easily.
Messaging: there is one downside to the messaging, if there is no service, the messaging app 'gives up' and says not delivered, where as my old BlackBerry Curve 9320 waited until there was service again. other than that its great and easy to navigate.
Safari (Web Browser): Safari can take multiple tabs easily and keep speed but processor does get a bit hot. it can be used portrait or landscape.
Mail: Mail is very quick and can be set to update manually to every 30mins. Can also take multiple email addresses as well. all in all a great phone and would recommend to anyone
