Just to update everyone here, my new 3GS phone was having problem with incoming call, couldn't hear anything thru earpiece.
I went to apple store and they told me to wait 5-10 business days and told it will be in white box. I called the apple care next day asked the same question whether it is refurbished or brand new. Apple care told me my replacement phone will be repaired one with new parts and two times QC'd. I requested to speak with his manager. Got nice lady on the phone, she told me she is manager of corporate customer care.
I told her that this is 5 days old phone why I would have repaired phone? if my phone is 2-3 months old, no problem. I haven't even used it. I told her I would like to have brand new sealed box like I got it from AT&T. She said no problem, created my order and my new iphone (BRAND NEW) ships straight from china.
Here is the S.No: 859315xxxxx and tracking info..My old phone was having S.no: 84927xxxxx
