I wish they would let us change the base colors. Pastel is so, so, sorry, its girly.
I just came in here to comment on this.
The color looks good to me, but to a whole lot of people, it's just going to look exceptionally bright and possibly 'toy'-like. I mean I can see their direction with it, but everyone else might just see this bright, pastel colored phone. It's such a giant direction change from the way iOS looked previously. This is something that could cause outrage with many, many people.
I'm excited to put it on my fiance's iPhone 4S and her mom's iPhone 4. I wish I still had an iPhone 5 to play with the new OS.
