Iphone Icon Changed

Hi When i start to develop my application , I used iPhone version 2.0.... Now i have update Iphone version 3.0..

My simulator works fine both in iphone 2.0 as well as开发者_高级运维 iphone 3.0..

But When i run my application in 2.0 all icons in the iphone should be correct . But when i run this in 3.0 my other applications icons are changed.... (Example my safari icon should be placed to itunes and itunes icon to settings likewise all icons changed)

I dont know why?

Can anyone help me?

THanks in advance.......

Apple updated the icons for most, if not all, of the system apps between 2.0 and 3.0. What you're seeing is expected behavior.
