Iphone 4s headphone jack not working? - 1

I've had an iphone 4s since last July and all of a sudden, my headphones stopped working. I found out that it wasn't my headphones, but it was the jack where you plug in the headphones! I have an old iphone 4s that is not being used but the power button doesn't work on it. Can anyone tell me how I can transfer my sim card into the old phone? Or do I have to go to an AT&T store to get a new phone or go back to another Iphone 4s?

I have iPhone for life plan with Sprint and they said they would give me $345?

So, I an older iPhone with a Tmobile plan and I went to Sprint because they said they could buy me out of my plan. Sprint owes me $345 since I ended my contract with Tmobile and switched to Sprint on the iPhone for life plan. I believed that once I got my terminating bill from Tmobile I would bring it to Sprint and they would give me the money. I owe Tmobile $424 and Sprint said they would give me $345 and I would pay the remaining balance. I went to Sprint and they told me they would reimburse me and that the money would take 10-12 weeks to get to me… So now I'm left paying the $424? I'm so confused, please help me out. Is there a way I can get the money Sprint owes me before 10-12 weeks? I can't afford to pay the $424…
