Iphone 4s speaker suddenly stops working

So I was just playing music on the iphone speaker and it just suddenly stopped working… I tried adjusting it but i can't even adjust the volume with the buttons… The ringtones and calls on speaker work just fine and the music plays just fine with headphones and the volume buttons only work when the headphones are in… I restored my phone already and it started working again… I was listening to music like 10 mins ago and then it suddenly stopped AGAIN… What the heck is wrong with my phone?

Why doesn't God give this to me?

A couple of weeks ago my old phone broke, that led me to searching on the internet for a new one when I found an Iphone giveaway. I signed up for it (the winner should have been announced at November 22nd ) a few weeks ago. So from then I prayed every day, I fasted and even I came across to the story about the woman who lost her house and everything she had and begged the unjust judge to give that back to her. He didn't wanted to but because she was annoying He gave it back (And it said if the unjust judge gave her what she wanted than God as a just one what would he do). And I continued praying and fasting. When the winner was supposed ti be announced (And it's in a different time zone so it was November 23rd which is my birthday) I believed that I would win but whit all hope I looked and the winner wasn't me.
So it was my birthday, I prayed and fasted for weeks and (I didn't fast the whole time) I believed that I would win but God still doesn't answer. Please don't put negative answers. Sorry if it was too long

Best Unlimited Option For iPhone 5s Unlocked?

I purchased an unlocked iPhone 5s last week and I'm having a difficult time finding a reasonable option for unlimited data, voice and text. I'm no longer interested in being on a contract. Boost Mobile would have been perfect but they don't allow you to bring your own iPhone and they don't sell nano sims. Have any of you come up with a creative solution? Surely I'm not asking for too much.
