According to your sig you have a 3GS. Have you used a 4 for more than a few mins and then tried to go back?
Also, I hope apple does not listen to people like you and up the screen size.
I prefer a smaller form factor with my phone.. I'm not watching movies on my phone, that's what my iPad is for, so why do I need a huge display on it.
I don't..
Besides, from what I read the technology is not there to make a 4" screen retina quality. And I hope apple will go backwards in dpi.
