No you don't. When you install it will stay the same with contacts emails and etc.

Absolutely. New softwares are prone to glitches and could mess up the data you have on your phone, so it's a must to backup everything.

Why isn't ios 7.0.4 installing properly? This has been happening for a while now since the update of ios 7 came out. I have an iphone. And it won't install. Whenever i click install it gives me an error it says verifying update but then a message pops up saying an error occurred while installing ios 7. I have good connection and over 50% battery. But i'm wondering on why ios7 is not installing on my iphone5 thanks in advance!
Should i replace the back of my iPhone 4 before i sell it? It cracked last year, but I just put a screen protector over it and continued using it. Now my contract is up, and I'm selling it&getting the iPhone 5. Should I replace the back glass (since its easy to replace) before selling it, or would that cost more? Which would be cheaper?

No sound after installing iOS 8? So this might be a stupid question, but I installed iOS 8 on my iPhone 5s on Wednesday and ever since I have had no sound on my phone when using apps such as YouTube. When I play music on my regular music app there's no problem. Any suggestions as to how to fix this? Any help would be much appreciated!
