Ordered a iPhone 4S 16GB Black (simfree) last friday on the UK Apple Online Store. I still managed to be in the "delivery by 14th of October" slot. Just a bit later it would change to "1-2 weeks" estimate. However, I am realising that I actually should go for the 32GB version. Do you think there is a way to modify my order without loosing my "waitlist position", i.e. delivery on launch day? My order is still being "processed", i.e. I could still cancel the whole thing.. What do you think would be the best to do?
