Anyways, for those who have called Apple and they confirmed a delivery date of 25th, check again.
I got that when I called them to double check two of my orders....
to my surprise they said that I will get it on the 25th due to high demands (I ordered within the first 5 mins after 12:00 that evening)
But I checked my tracking this morning and found out that it shows something different on the UPS site.
I think Apple is just giving a later date to be safe and no one will ever bitch at them for a phone arriving early but if it arrives late; hell will break lose.
Good Luck everyone!
