Get rid of green text when messaging Android phones

Do you mean green background? Because the non-iMessage bubbles are the white text on a green background for outgoing messages only. Given that the most vocal folks seem to be Android users who care about the background color of someone else's messages I doubt the majority of iPhone users care, would notice, or are even using the Messages app in the first place. Certainly if you're calling it green text you're not paying much attention either.

  Better camera (arguably already achieved)

Apple can still get rid of that hideous camera bump.
