IPhone won't turn off and won't dock properly?

I have an iPhone 4S that I got justa little over a year ago. I got a small sony dock for Christmas, and my phone would ot play music through it, but all the other devices I tried worked fine. I got an iHome id50 because it said it would work with the iPhone 4S, it works perfect on blutooth, sometimes when docked, and never does the auto-adjust time feature. I tried many other iPhones and they all worked, Including another iPhone 4S. I have the latest software on my phone and when docked it always shows that is is chargingso I know it docked correctly. Lately I have been getting an error saying that the dock is compatable with my phone, but if I take it off and put it back on it seems like the message never come back twice. My other Problem is that I can't turn my phone off. When I hold the power button, I get the slider to turn it off but after I turn my phone off it just starts up again without any buttons being pushed. I tried a hard reset and a software update but neither fixed the problem. Does anyone have answers to any of my questions?

My laptop will connect to public Wi-Fi but won't get internet?

I have a sony vaoi running windows 7. Now at home my Wi-Fi connection is perfect, but when I'm at a public place, best western at the moment, i can connect to the public Wi-Fi but when i open my browser (google chrome) it won't come up with the webpage where you have to accept the best western terms and agreements. So it won't access the internet at all. I also tried it with internet explorer to no avail. My iPhone however will pull up the authentication webpage no problem, allowing me to access full internet so i'm pretty sure its something to do with my computer. Thanks in advance!

Should I upgrade to the iPhone 4S or wait for the Samsung Galaxy S4?

I have the option to upgrade from my old black berry curve to the iphone 4s for free, or I can wait a month to get the samsung galaxy s4. Also for free.

Added (1). Sorry I made a mistake, the Samsung Galaxy S4 I would have to pay for that one but it would be cheaper for me because I'm upgrading.

What's the best iOS an iphone 3GS can upgrade to?

I was considering getting an iphone 3GS because they are very cheap (even though they are old) but i didn't know what the best iOS to upgrade it with would be without it playing up and getting slow. Please help. Also could i buy an iphone and then just get an iphone pay as you go sim?

What incentives can I expect for upgrading to iPhone 5 with O2 at end of contract?

At the end of April 2013, I complete my 24 month contract with O2 and the iPhone 4. At the end of March 2013 I can upgrade to the iPhone 5 a month early.

I see that a new customer can get the iPhone 5 64GB for £209.99 and also have to pay £47 (I currently pay about £43) per month for 24 months, so what incentive can I expect for upgrading rather than just signing up as a new customer or just going elsewhere?

A cheaper iPhone, lower monthly fee or something else?

Why is my iPhone 4 memory low?

I checked the settings and it says capacity 6.3 GB and available 1.1 GB

But I hardly have anything on my phone?
2 songs, 7 videos, 315 pictures and 18 apps.
Shouldn't my available space be more than just 1.1?

And also, would I lose my pictures and everything if I jailbreak it? And how would I jailbreak it?
