I expect the screen of iPhone to be bigger. I have found most people like a bigger screen. You get to see the numbers, messages clearly. I am sure that iPhone will have larger screen.
I saw some of the pictures that Apple released as a an example of what the phone will look like and the screen looks to be about the same size as an Ipod screen.
I thought that the screen looked like the size of an ipod screen also. I think it depends on each individual person though as to what their preferences are, some like the the screen to be bigger and some like the small ones.
I am not sure on the screen size but i think it is about time someone do one with a screen that is easy to read, I heard from others though that the screen was about the size of an ipod.
I would love a bigger screen and clear characters. If it is like an iPod screen then I think it would be easier to read. I really do not like the screens offered in some phones which are currently available in the market.
It's the time of big screens. I do not know what will be the screen size of iPhone but it will have a better appeal if the screen is bigger. As things stand now we will only know about it later.
