My iPhone 4 won't turn on, What can i do?

So i'm having a bit of an odd problem with my iPhone. Yesterday it ran out of power and since then i haven't been able to turn it back on. When i plug it in to my computer or a wall charger it will flash to apple logo for about 15 seconds and then it just turns off again without reaching the home screen. However if i plug it into my docking station it powers on and goes to the reset screen where it tells me to plug it into iTunes but as soon as i disconnect it from the docking station it turns off again despite it saying it has 100% charge. I've tried doing the hold the sleep button for 2 seconds then hold the home button thing but that hasn't worked.getting it replaced will cost me £50 so i want to see if i can get it working any other way first so is there anything i should try first?

Jailbreaking slows down you iPhone?

Hi, I've jail broken many times and I know it will only slow down your i device if you add a bunch of useless tweaks. My question is, if I did decide to download a lot of tweaks and it slowed my iPhone down, would doing a restore bring it completely back to normal? Or would it still be slower than before I jail broke it?

How to set a song for a ringtone for iphone 4s?

I have followed previous directions about changing the song extension, but it won't add it to my itunes. The phone is synched. I have purchased the song through the store from the ringers folder, but the song is not listed as a ringer, and won't let me choose it. Is the updated version of itunes prohibiting me for adding the file? Does iphone let you transfer files to it when plugged into the computer or does everything have to go through itunes? It is driving me crazy! I have researched this and done everything I can think of.

HOW does iPhones and other newer forms of technology adjust to Daylight Savings Time?

So today was DST, time to change our clocks, but I already knew for a long time, that advanced forms of electronics like most smart phones and modern computers would automatically adjust, and I wonder, how? I searched online and could only find questions like "will my iPhone adjust to DST?", or "all my schedule was delayed by an hour, why?" These are questions that I feel for people who never paid any attention to their devices before.

Some articles I read suggested that connectivity to networks such as the Internet will notify the device and that turning on Airplane Mode may prevent the automatic adjustment. Some articles I read asks questions like "Will my phone adjust to DST?" That got an answer like "yes, my wife's and my phone did. We use T-Mobil". Why is phone carriers involved? Without being able to have service, how does iPods and some iPads still adjust? What about offline computers? They all seem to do fine.

What I'm interested in is HOW? How does these devices know when to change and which direction to change? What are the processes that goes on to make the change happen?

How to play games without internet connection on iPhone?

I have an iPhone 4 with iOS 6.1.2.
When I launch games like Zenonia 5 or Dead Trigger, Zenonia 5 asks for internet connection and Dead Trigger crashes if I'm not connected to Wi-Fi, but the both of them run perfectly when I'm connected, and of course I don't want that. I want to play whenever I want without the need of being connected to the internet.
Is there any method that would let me bypass the check? Or a way that would disable that check and make me appear as connected to that app?
Thanks in advance!

Added (1). Forgot to mention: that these 2 games can be played offline. I mean they aren't MMOs (single player story line).so.
