mmm... sorry if i put in the wrong sentences... let me try to understand better.
i freshly put in my contact 1 by 1 brand new to the iPhone already. So i don't wanna delete or crash my head if i had to redo a few hundred contacts lol.
Sync your contacts with Ms Outlook using Itunes.
- so whatever i have in the phone i sync to MS Outlook? or does this only sync the sim card data?
Delete all the contacts in Ms Outlook and sync your Iphone again.
- wouldn't this like delete my whole address book hence the bottom point?
I believe this will empty your contact list in the iphone.
- omg i'll kill myself(?)
Import Sim contact back to your Iphone again.
- hmmm old data?
-------------------------
i think i fail in asking questions

What my main concern is, how do i delete all my old data from my simcard which is already in the iphone? (without touching my existing address book which i created fresh from the oven)
