What should i do with my iCloud account?

Okay so i had gotten my iphone last christmas and my phone company was sprint. A couple months later my parents decided to switch to verizon when we were at best buy. When we made the switch i had lost everything on my phone and i had to spend 4 hours in best buy rebooting everything back onto my phone. After the process of rebooting everything i had to make a new icloud account. And i guess i had two passwords for it. When i wanted to make a purchase i had to type in both passwords because one would show up incorrect than the other. It finally decided to disable me from all app purchasing and now i can't buy or download anything. My phone has been like this for almost a year. I don't know if i should delete my account but that would mean losing my email address. Sorry for the long story.

Recently my iphone 4s stopped recognizing any Wi-Fi networks, i did some research and seems that a lot of people have this problem howeverthe new iOS 6.0.2 update is only availible for iphone 5 and ipad mini.
I have pretty much tried everything that i can possibly do to try and fix the issue but nothing works.

And does this mean my Iphone 4s is broken? Or it can't be fixed?
