How to make an iPhone 5 case fit an iPhone 4S?

I have an iPhone 4S and today I bought this really cute phone case from H&M, it's silicone and glows in the dark! The thing is, once I took it out the packet and started to put it on my phone, I realised it's for an iPhone 5. --- It says it on the back in TINY writing. Does anyone have any suggestions on how I can make it work?

Android can't receive photos from iPhone 5?

I have the Samsung galaxy nexus on telus and I'm able to receive photos through text from everyone including android and iPhone users except for people who have the iPhone 5, for them it shows up as a blank mms is there any way to get around this or fix this? Restart doesn't help

I can only hear iPhone sound when using headphones?

My volume is turned up, without headphones I can hear the keyboard sounds, the phone ringing, the sound when I get or send an imsg - but I can't hear audio like music in games, YouTube audio, my friends' voices in the app heytell, etc.
I tried a "hard" restart (where you hold down the two buttons for a few seconds and it turns off), I've tried reinstalling said apps. Don't know what to do now.
Btw I have an iPhone 3GS and just last week I switched to tmobile from AT&T, had to unlock phone, but as of yesterday the sounds were working just fine?

Not getting calls on iPhone

Okay, long story short, I'm a realtor and my job fully relies on my phone. I started having problems yesterday when I was sitting in training and my phone vibrated. I had a voicemail, but it had not vibrated with a call. I didn't think much of it but then when I was driving I looked at my phone again and I had a voicemail. It didn't ring. After that I had my mom call me to see if it was working and it rang fine.

I had my phone with me for the rest of the day until I went to my night job at 5. Occasionally I peeked at it. I got a few text messages but no calls. When I got home at around 9:30, I noticed that I had a voicemail from 4:11 earlier that day. And that was before I went to work when I had my phone with me.

Then this morning my mom called me again and told me that I had someone who wanted to sign a contract with me not being able to get a hold of me! My phone has been sitting next to me all morning and I only got a call from my mom. I don't even have any missed calls!

This needs fixed now. If we didn't know these people I would have lost pretty much $7, 000

I have an iPhone 4S with Sprint. Could I have accidentally changed a setting? How can I get this fixed, what do I do?

Added (1). Also, "Do Not Disturb" is not on.

IPhone 4 charging for days but won't turn on, any

I have an iPhone 4 (not 4s) that i bought about 6 months ago. Lately it has been turning off when it has full power or even while still in the charger. I put it in the charger and it can take days to turn back on. While in the charger it shows the empty battery and charging sign. When it does turn back on it lasts for a day or a half before needing charging again. I have tried resetting it but that did nothing to help. This is causing a lot of problems and any help would be appreciated.
