BS

I don't know what S2 your talking about but I have an AT&T GSII and 4S. It's barely bigger then my 4 or 4S at 4.3", and a little thinner actually. Laggy? Uhhh no, buttery smooth and fast. Blank screen?? Uhhh it's just like the iphone, it's blank durring talking, the second you move or do something it goes back on.. you know... just like the iphone and pretty much any phone

. Random calls??? sure... Looks? Well that's subjective, 4/4S look great, too bad we have to have a case on them hiding any beauty since it's not a matter of if, it's a matter of when it will get dropped or knocked off. I'm not saying it looks better than the 4S/4, but fail to see how the GSII is ugly. It's thin, shaped very well and looks sharp and classy with the capacitive buttons, the design as far as looks is always a standout point in any reviews that even mention that point.
sorry but I love calling out post like this as I still own an 4 and 3GS in addition to the 4S. GSII is simple, I mean what else do you want. Want to make a call, press the phone icon, want to text, press the text icon, want to go online, press the browser icon. Man is that complicated lol. Where the difference is, if somebody wants, there is a ton of customization you can do to it stock which I prefer. Same reason I jailbreak the iPhones to get rid of Apples restrictions.
the "just works" is so overused, you mean the same "just works" that has had a bunch of issues and glitches lol. Not to say Android is issue free, but Apple isn't either.
