White or black, iPhone is still the same iPhone.
If it ever arrives in Malaysia, best thing to do is just to layan it then go ahead with other things in life.

What you want to wait is iPhone 5! And there are rumours that because of the arrival of iPhone 4 white, the iPhone 5 might arrive next year instead of the anticipated this year.
