New iPhone announcement on Wednesday. When will the 6 drop in price? Same day?

I've been waiting for the release of the new iPhone so that the price will drop on the old one as it does every time. I did the same thing when the last iPhone came out. Remind me: Does the price of the old phone go down the same day as the announcement? Like can I get my new phone on Wednesday? Or will it be the next day? Or does it drop when the new one is actually released? Can't remember. Thanks!

Added (1). Also, do I need to wait until my contract is up on Sept. 14?

IPhone 5s is having problems receiving calls?

My iPhone has just started having problems with receiving calls from any phone. I have not changed any settings in my phone to cause this problem, people will call me, it may ring once or twice on their end of the call but then it will either say it's busy or go straight to my voice mail, I do not receive anything on my phone indicating that someone has called me. I tried the entire list of things Apple has listed in their help page for this issue and nothing seems to work. Now and then a call will make it through but most times it will not. I have not dropped my phone or damaged it in any way, IIm not in a area of bad connection, I frequently talk on my phone and have never experienced this issue before. I've tried taking out the SIM card and resetting the network settings, I've checked the do not disturb option, I have not yet reset my phone as I do not want to go through that hassle. If anyone has had this same problem, please help.

My jailbroke iphone 4s won't turn on?

Like i will reboot it and it restarts to my lockscreen but i can't swipe right or anything. Then it locks but its not completely locked, i can't turn it on and see the screen, but i can use siri?! Please help this is my only phone my other iphone 4 just broke a few days ago.
On this jailbroken phone the only thing i can think that is causing the problem is my springtomize 3 setting which has it to where it has an old tv lock (where it comes from the top and bottom at the same time and closes)
