I would recommend the Galaxy S3, and heres why. Comparing iOS and Android, Android wins. Face it, you can swap out any component of android for another with a simple download (Change your lockscreen, keyboard, application manager, layout, homescreen functionality, etc...). To get that kind of functionality on iOS you need to jailbreak it. Also, you can root an Android and it doesn't void your warranty (under samsung) giving you even more power. Android has a faster growing library of apps than iOS since the Dev Kit is easier to use. I have more, but I think that suffices. As for the Nokia, I wouldnt say its bad but its not the greatest. Windows phones have issues with the OS. While it integrates well with Microsoft services, it just seems like memory creep and crashes happen too often. Maybe in a year or two ms will fix up their OS. Blackberry, well theyve been on the decline for a while now. If you like functionality without all the extra, then this would be a good phone. Dont misunderstand me, its not that blackberry is minimalistic, its just that it doesnt compete with Android on things like app capability or customizability.
