Hi... i have a iphone4s and my wifi greyed out right after i upgraded it to f*cking IOS 7.1.2... Im so regret because not only my wifi not working, even the battery is finishing really fast.

So i'm wondering if you had experienced any customer with the same issue as me?
What is your suggestion?
Can i jailbreak it back to IOS 5.1.1?
If i do, will my wifi be working again?
and if i do jailbreak to IOS 5.1.1, will my battery usage back to normal as previously?

I really miss the old IOS 5 phone, everything was so nice.
Now i hate my phone already... Please help
