Like 3D on phones is already out overseas in Asia, China... somewhere over there.
About mainstreaming....look at front facing cameras on recent phones. First, phones from years ago had it already. So its nothing new.
Between Android and the iPhone it came out on the EVO first. But most iFans during and right after the launch of the iPhone 4 mentioned FFC like it was something the iPhone had and Android didnt...lol Or like Apple invented FFC.
Some iFans and regular iPhone users (yea there is a difference between a fanatic and a user) think the iPhone 4 is the only phone in the world with that screen resolution. I had to remind someone that there is a Chinese Android phone with the same resolution.
So the iPhone having it will probably get it more attention, just because its on the iPhone. I'm not discounting Android and how far they have come, but Apple is like a household name. Funny thing is, Android is just as much of a household name in my area now too. I live in the DC, MD, VA area.
