IPhone 4 turns off by itself?

I got an iphone 4 a couple of days ago. I updated it to the latest iOS and everything was working fine. This morning I was on it for a few minutes and put it in my pocket. When I took it back out a couple of minutes later, to my surprise the lock screen would not come up. Assuming it had turned off, I tried to power it on, and it wouldn't. I held down the lock button and the home button together as well, and that didn't work either. Then around lunchtime, i tried to turn it on again and it did. Soon after my lock screen came up, it turned off by itself again. I tried powering it back on and it worked (for once). The phone functioned normally for about 20 minutes. I put it back in my pocket and when I got it back out later, again, it had powered itself off and I could not turn it back on. I just got home and plugged it in to itunes, and it came up saying that my phone is in recovery mode and that it must be restored to factory settings. So now I'm waiting for it to be restored.

My question is, what causes this? And is there any way to prevent it from happening again? It's quite frustrating, and I've seen many posts online related to this, so many people are experiencing the same problem.

IPhone 5 crack but not the screen?

Iphone 5 crack (not screen)?
I'm scared that if I drop my phone one more time then the crack will just expand down the whole screen.

It starts halfway across the speaker at the top (front) of the phone and goes right to the edge of my phone narrowly avoiding the screen.

How much (estimate) would it cost to repair this crack before it gets worse?

How can I prevent it cracking anymore (and don't say look after it more or don't drop it) is there any ways?

What is a good set of speakers or sound system for a somewhat low price?

I'm looking for a speaker system that i can play my music out of. I have no idea what the speaker market is like. I'm looking for something that sounds great and will definitely have amazing bass (I love trap music). Nothing huge but large enough to make it LOUD. I'm not great with audio systems, so it has to be somewhat simple(although my dad is actually a professional at this, he doesn't have the passion or money to get a new sound system). I would like to be able to connect my ipod, computer, and future iphone to it. I have a smaller bluetooth speaker with an output so i can connect my 3.5 mm audio jack to it or use a quarter inch adapter with it, giving the system bluetooth powers. I don't have a lot of money and it would probably be a birthday present or something, so I'm looking in the less than 300$ range. Any suggestions are greatly appreciated!
TL;DR
big bass
easy to use
300$

How to know if someone blocked your iMessage?

On the iPhone ios7 I know there's a feature where you can block someone from iMessaging you, I was just curious as to if you are the one being blocked, is there a way you will know? Or will messages continue to appear as normal and you sent them?

Horse lease issues- Help (additional)?

About 5 months ago I was leasing a horse. I paid the full two months up front because the owners would not allow day by day pay. 3 weeks into the lease I fell off and seriously got injured which resulted in not riding for 2 months for recovery. The owners said no refunds(the contract didn't mention it, but I could come back once I've recovered to finish off my lease. I'm better now and would like to finish off my lease but the owners are ignoring me and not replying to texts (I have an iPhone and shows whether a person has read your message) and phone calls. What can I do? Am I in the wrong or is the owner wrong for ignoring me and taking my money?

To add
Yes there was a written contract that I signed (she did not give me a copy when I asked for it), I fell off a different horse not my lease horse (the horse spooked then bolted and I fell when he had a little trip), I have multiple messages that the owner said he will let me finish off the lease because they won't refund.

Why won't my iTunes recognize my iPhone 5c anymore?

My iTunes used to always recognize my iPhone, even my laptop right away had something pop up for it when I plugged it in. My brother recently got a new iPhone so he signed into his iTunes and ever since nothing happens when I plug my phone in besides charge it, same for my brother. Is it because he signed in or also because I just updated iTunes? I've tried restarting both my iPhone and laptop.

Why isn't my iPhone 5S syncing all my music?

I have just bought an iPhone 5S and updated all the latest software and everything has backed up from my old iPhone 4S perfectly, except for my music. I have 191 songs on my iTunes library but my phone is only syncing 97 of them. How can I get all my music in my library synced to my phone?

I have tried looking on forums but nothing worked. Someone said to tick 'convert higher bit rate songs' in the summery section of the iTunes library but that didn't work. I tried making a playlist with all my songs in and syncing it to my phone but only the 97 songs showed up on it. I'm really at a loss of what to do and won't be able to get to the Apple Store until tomorrow afternoon. Can you please help me?

Is college the only way to success? - 1

I would just like to know your opinions, and if you believe college is the only way to be successful? We're all born knowing and believing that college is very important in order to be successful; But do you believe this is true? The reason for asking such a question is because I've been thinking about dropping out of college and pursuing my dream as an entrepreneur. Here's my story,

I'm a 19 year old guy, about to turn 20 soon and I've been self employed for quite awhile now. I consider what I do as a 'business'. I design websites for my clients and I'm earning equally if not more than I would in a part time job; depending on how well I market my business. I'm also writing an ebook at the moment about my success and my dreams in hopes of inspiring others, and I do believe this book will be a success.

On top of that, I'm attending college twice a week and I'm in the process of publishing my first iPhone application which I also believe will be a success. I'm a very optimistic guy, and I'm a true believer that it's not about how good the product or the service is, but how well you can market it.

I've also been really interested in the stock market and I been saving about 80 percent of all my earnings as I plan to use most on investments. I have pretty high standards and a big goal I plan to achieve, now the question is. I know it's a risk i'm willing to take, but is college really the only way?

Why does my iPhone 5s die so quickly?

It does within 5 hours. Barely on it I just click the power button to check the time and it constantly decreases. I've watched it go down like a clock. What tf is happening to my phone.
