Hello guys, I'm very curious about this. I currently own an iPhone 3GS and had a 3G before. So I don't know what to say about the iPhone 4's Retina Display, since I haven't seen one in person, cause the iPhone 4 isn't available in my country yet. Just wanna know if the screen is a true reason to upgrade. Feel free to post your iPhone 4 vs iPhone (3GS,3G,2G) screens side by side, just to tell the difference.
