Iphone4s or Samsung s2?

[Sader]

Both phones offer quite similar features. You can basically text, browse the internet, surf on Youtube, log in to Facebook, Instagram, Twitter, take beautiful photos and download hundreds and thousands of apps with both devices. S2 obviously has bigger screen than the 4S so it's up to your own preferences. The only thing about S2 is that it does not have S voice. S2 only works with voice command which is different from S voice while the Siri on the iPhone is much more reliable and helpful to help you with organizing things. So personally I'd prefer 4S over S2.
