Want to download iOS 8 but my iPhone says it's up to date?

I have a iPhone 4 and seen everyone posting about new iOS 8. Normally when a new update comes out my iPhone tells me but it hasn't. When I go to general and then software update it says my software is up to date with iOS 7.1.2 how do I get iOS 8?

How to factory reset a broken iPhone? (details bellow)?

I need to return my iPhone to factory settings. The problem is that my touch screen does not work, there's no picture showing, and I also have a passcode protecting my phone. Plugging it in and asking to reset it comes up with the "turn off find my iPhone" typical response and also my phone does not show up on Find My iPhone, so I can't just reset it.

IPhone 5S, 5C or 6 for durability?

I need some advice.

I've had 3 samsung galaxy S3 and 4. But I've shattered all of them. My last one I dropped once face down 3 feet high and it barely cracked but the screen was completely dysfunctional. That to me is ridiculous, I don't want one again.

Secondly, I've always wanted an iPhone considering I carry my iPod everywhere with me. However, I want the most durable phone I can get (I would have a medium sized case on it, like an otter box)

So I want an iPhone more than a samsung because of my experience. But do you think the 5C or 5S are more durable than the 6? I've watched drop tests but I can't tell. I wanna know from someone's experience. I held my friends iphone 6 today and feel like it was very delicate. So I was thinking of getting the 5. What do you think?

Should i convert from androif to Iphone 6, or wait?

I'm an android user from the start. I own the nexus 5 currently and without a doubt it hasn't let me down for almost a year now. I do wanted to have a iphone more than once but the idea didn't stick long enough. Now i'm waiting for the nexus 6/X but i won't buy it just yet. I will buy my next phone next year when the next wave of next gen phones come out. So my question is… Should i buy the iphone 6 or wait for s6 or htc one something else or nexus 6?

I can't find my iphone but I know it's in my house?

I lost my iphone today, and I still can't find it. I know that it's in my house, but my memory veers off when i try to think of where i left it. I do not have the find my iphone app, and i've tried calling it numerous times. What should i do? (I've looked everywhere, even unusal places)
