Need iPhone help Sound stopped working?

So I was playing a game and the sound all of a sudden stopped. And I went to Spotify to see if it would work there. Well, it plays but there's no sound. I turned off my phone and turned it back on. Still nothing. And when I hit the "volume up", it just says "Ringer" or "Volume" with no volume bars… This has never happened.

Iphone 4 keeps turning off?

My iphone keeps turning off when i unplug it from the charger. Sometimes i'll leave it charging for like 2 hours and it will stay in the same percentage i left it on and it will turn off when i unplug it. Its not the charger!

How long does it take to fix an iPhone 4 screen?

My nephew cracked my screen and I'm taking it in to a local store tomorrow to get it fixed. How long should it take for him to replace the screen? The guy said he'd fix the front and the back, though the back isn't cracked. He isn't charging extra for the back, though, so I don't care.

Tips for cross-country drive?

Soon I will be driving from north Ohio to western Texas. I have never made a drive this long before, and I was wondering if you could give me any tips you have. For example, can you trust the gps on your iPhone to get you there? It says it will be a 22hr drive, but after factoring in traffic and rest stops I figured it would take more than a day. Where is the safest place to stop and sleep? Is it more realistic to just book a hotel for a night?

This next part will sound dumb but I have a phobia of tornados (yes I realize i need to expect them in Texas) and I'm paranoid that I'm going to run into one during the drive. What if I'm out in the middle of no where and there's no place to go inside? I get stomach pain just thinking about it.

Anyhow, and advice on making a cross-county drive will be greatly appreciated.

What is a good weather alert App?

I already have a basic app that gives me the basic weather. What I'm looking for is an app that will text me or 'go off' for a severe weather alert. That way i can get important alerts if i, for example; get a overnight tornado warning in my area, and i'm sleeping and wouldn't see the warning otherwise.

I have an iphone, Thanks!

How would the world work if time travel was possible?

If time travel was possible and the public could go back in time, then could they alter the things that happened in the past? And if so, then wouldn't some ppl with bad intentions try to do something like for example: bring an iPhone to the Roman era?
( or something like that ) and if that happened, then wouldn't the technology nowadays be more sophisticated than it already is? If people could really alter the past, then how would the world be governed? Could only specific people access the time machine?

I know I'm asking a lot of questions, but this is a really interesting topic and I'm really curious to know what will happen
