When would be the best time to get the iphone 6?

Ok so today is tuesday september 16 and the iphone 6 comes out on friday i was going to preorder but tmobile says that its on backorder but i still have to pay the monthly charge even though i don't have the phone so i just decided to wait until its actually in stores but there has been a lot of preorders (4 million in just 24 hours) so if i go and try to get it release date theyll probably be sold out already so i was wondering when would be the best time to buy it november? Or December christmas t ime? Thanks in advanced i know its long i just need some help.

Why aren't there ever new stuff in movies?

I know the question sounds weird but I meant it as, why isn't there ever the new iPhone in movies or any new cell phone, why is there always a phone that is like 2-3 years old? For example. I was watching the movie War Games: The Dead Code and I saw Will Farmer (Matt Lanter) was using a Palm Treo. That phone came out 2 years maybe 3 before the movie released. And he was also using a PowerBook G4 12in. Why didn't they just give him a MacBook from 2006 instead of a laptop from 2004 cause the movie was released in 2008. And i saw a recent movie (I can't remember the name) some kid was using an iPhone 2G and he was using and a MacBook Pro (2007) model… And this movie was released in 2012 or 2013. Why can't they easily put newer Apple products in movies cause I know Apple doesn't pay for product placements.

My iPhone 5 won't slide to unlock?

The on/button stopped working recently so I can't reset it. I've been using it fine but all of a sudden my iPhone won't slide to unlock. When I get a notification I can't unlock it that way either.
I'm not sure what I can do?
iPhone 5 about 20 months old.
