TiPb's done an iPhone 4 preview but I'm still curious -- which iPhone 4 feature are you most looking forward to? Did Apple have you at FaceTime? Are you drooling over that massively dense Retina Display? Or is it the hot custom silicon in the Apple A4 chipset that gets you going? With over 600,000 pre-orders the first day, something sure is making Apple's newest handset popular.

NOTE: We didn't include multitasking, folders, or similar features since those are more properly iOS 4 related and we'll have a separate poll up for that tomorrow!

Check your answer in the poll above, then tell us why in the comments.
