Rather than ragging on the OP for caring what others think (like EVERYONE does by the way... they just lie about it to try and hide their own insecurities), I will first say this: Given the choice, MORE MEN choose the black, and MORE WOMEN choose the silver/white.
It is what it is. It doesn't make it girly per se, but the silver/white is preferred by women and the black is preferred by men.
If you like the silver more, get it. If you care about what other people think enough to have it influence that decision (and there is NOTHING wrong with that) then get the black.
High end phones (especially the iPhone) are status symbols. People can bemoan that all they want, but it's fact even if they don't think of it that way themselves. Apple sure does, otherwise they wouldn't describe the phone using all of the "beauty" words they do. It's fashionable. Period.
So if you aren't concenred with what people think of your fashion choices, good for you, but most people are (and I'd venture to call you a liar anyway).
The OP had the courage to admit to actually caring what others think. You can crush him for that, or realize that we ALL do, just some more than others, and answer his question.
Sheesh
