Xperia S. Stunning looks and great all round performance.
4S, no doubt!
Nokia 100, no questions asked!
That's a great line-up! I had to add my favourite phone though, the Nokia 100. It is a nice, no-nonsense mobile with outstanding stand-by time without compromising style. And, it's got colour screen as well at an affordable price!
Not easy to choose between theese 4 mobiles. Good taste btw
