Problem with home button/iOS7 update?

I'm not sure if it's just me having this problem, but ever since I've updated my iphone to the iOS 7 update, my home button seems less… Responsive? Everytime I try and open siri up, the multitasking pages come up, even when I press the home button hard enough, and I leave my finger pressing down on the home button so siri should come up. I have an iPhone 4S. And sometimes the home button is unresponsive completely for a few seconds but when I try again it seems to work. I've never dropped my phone, got it wet a few times but it's worked fine since then. Never had this home button problem before. Any ideas why this is happening?

Two iPhones using the same Apple ID account

I recently got the iPhone 5S and everything is fine with that. Prior to that, I had the iPhone 4S. The 5S is activated with my cell provider and the 4S has been deactivated. I want to use the 4S sort of like an iPod Touch. I'm using the same Apple ID on both devices. Whatever I do on one, take pics, edit contacts, etc, it shows up on the other device. I was wondering if there's a way to use the same Apple ID but not have the changes transfer over to the other device?

All of my apps on my iphone keep crashing since iOS 7?

I installed ios 7 onto my iphone 4; though it kept cancelling and not installing it and there was a moment where it was stuck in recovery mode and wouldn't go further. But now that i've got it all sorted, all of my apps keep crashing. This isn't just apps that haven't been ios 7 prepared or apps that have been, but it's usually all of them. Not just apps like Facebook, but like Mail and Safari just won't let me into them. I tried restore and the phone was fine again… For the night, but the next morning it was back to being crap again.
ios 7 has genuinely destroyed my phone.

Is anyone else having this problem or found a way to solve it?

Does Sprint charge an activation fee on the Pay as You Go plan?

I'm looking for a new phone (new costumer) at sprint. I have my eyes on the IPhone 4s, I filled it all out already online to see how much it would cost when I buy it next week so I know, the pay as you go is 70 a month for a smartphone, and the cost of the iphone is 100.00$.so I was wondering if sprint charges an activation fee also to their costumers? I'm really bad when it comes to buying phones lol
