I don't think they are being mean, I think they want these phones to be available to every one who wants one - why wouldn't they?
My thinking is that there has to be some White iPhones produced and ready to ship out but for some very good reason there will not be enough to go around on the 24th. By not allowing for pre-orders they can make sure that the few that are out there ready for sale can be more evenly distributed through out the regions where the new iPhone will be made available on launch day.
Its true I am speculating and maybe this subject is getting old for some of you but why do folks willingly step into a conversation just to announce that they are bored with the topic of choice.
Everybody didn't show up to this "party" early and some of us would like a chance to exchange our thoughts and opinions with those that are currently interested in this topic.
You had to of known from the heading that this thread was about something you didn't care about so why bother reading or posting if you don't care?
