My iPhone 5 charger won't work?

I've had 5 iPhone chargers since December 2012.
I'm getting tired of paying $20 for a new one almost every other month, and having the guy at the at&t store blaming me for not using it correctly when I do.
I refuse to buy another charger. What should I do?

My iphone 4 won't connect to my Wi-Fi?

So about a week ago i dropped my iphone so i went to the apple store and got a new one. I brought it home i was really excited but it wouldnt connect to my Wi-Fi. I entered the correct password but i was unable to join. My ps3, my sister's laptop, my mom's laptop and my sister's iphone are all connected to the Wi-Fi. I tried resetting the network settings but that didn't help. Can i please have other suggestions
