what so iphon-ish about it
Just look at the way you can browse album art. And the way you choose a song from that. Just the font is a bit different , haha.
The image gallery.
Kinetic scrolling.
Pinch and zoom.
Swiping pictures to go to the next one ( symbian does have this now although it is pretty slow)
Everything except the multi-tasking (which will be available in iphone os 4.0 in a few months).
symbian is the largest,and most used os out there ,it consumed more then 60% of market shares ,
At the moment it is just terrible to use.
I think you should look into why it is so widely used.
so its need overhauling ,thats what nokia is doing now
And ripping everything off Apple And Android. 
i dont see multiple home pages on i phone + creating as pages as u like
I really don't see the point of multiple home screens. Its the HOME screen , the whole point is that there should be ONE.
And btw , i'm pretty sure they ripped that off Android. 
i can take call and play music in background
You want music playing while you're on a call? :S
surfing the net , playing the music on the back ground & replying to text msgs at the same time,!
Actually you can play music and surf the web at the same time on the iphone. 
Btw i don't even use an iphone , i have a nokia and sony ericsson. 
Thankfully not one of the touch screen ones though , horrible to use. Haven't tried the N900 yet though.
