IPhone 4S: Wi-Fi problem in Settings app?

This is ridiculous, I was just using my iPhone when it suddenly disconnected from Wi-Fi. I went into the Settings app, I tapped on "Wi-Fi" and it froze there (only the app was frozen, I could still close it). So I close it and tried several times until finally I went into the Wi-Fi setting. It was searching for connections but it just kept searching and didn't even show up my Wi-Fi connection. I tried resetting it by holding down the sleep button (the one used to lock/unlock iPhones) and home button simultaneously but it still didn't work. I've also tried normal restart by first shutting it down and let it boot up again, problem is still there.

What's the steps I should do next? Should I restore my iPhone or wait for it to magically repair itself?

Sometimes it got worse till the whole iOS froze up for about 10+ seconds. Other apps work perfectly fine. Other settings in Settings app are still accessible.

Running on iOS 7.1.1.

How are they seeing my search history? IPhone?

Before I was suspicious but now I'm certain that my friends have access to my safari search history because every time I search something they bring it up not long after - and its pretty specific stuff and sometimes exact questions I have asked and they all have this look on their face- so I'm pretty certain they know! My question is how? What ways are there that someone could gain your browsing history- I have an iPhone and use safari and they have iphones and ipads so i'm sure its from my iPhone but I also have a laptop that's not apple so its probably not through that. I have private browsing turned on but they still bring up stuff and exact questions I have googled so I'm really confused and worried. How else would they be able to gain access? I thought private browsing was meant to stop this completely or is there other ways this could be happening? I don't really clear my history but I thought this wasn't needed because i'm on private browsing? Checked to see if it could be facebook and it said searches don't go over facebook so what is it?! Please help, very worried and embarrassed. I have an iPhone 4!

I have my teachers number and I like him

I'm in year 12 and I'm leaving school this year because I won't be doing A2, and well there's this teacher i'll call him Mr.J and we've been friends since the beginning of the year, I like all the other girls had a tiny bit of a crush on him when he came in September, his quite good looking and only 25. But obviously I thought it was kinda silly liking a teacher so I didn't really think twice about it just that he was a hot guy, but then I got him for science and everything was normal until one day when I was in lesson I had my iphone playing Jimi Hendrix and he saw and he came over and we just started talking about music, like actually speaking to each other like friends, we like the same music and that sparked everything off, I would almost every lesson we had before break or lunch stay behind and just speak to him, literally about anything, I think his so funny and smart and kinda sweet, when my ex-boyfriend broke up with me he told me he didn't know what he was missing and I was like not much and he laughed and he went if only your were 5 years older quietly and I was like what sir and he just laughed and said nothing, he also tells me everything about himself I think he might like me oh and on the day of my last test I saw him in the parking lot and he gave me his number and said to call him when I leave, is this illegal? I like him and I want to remain friends with him when I leave so maybe we can have a shot at a proper relationship i like him, help? What to should I do

US Army: Should I cancel my AT&T iPhone 4 contract?

I'm leaving next week to report to my first duty station in Korea. I have a US iPhone 4 from AT&T. I'm on the 2 year contract. Will my iPhone work in Korea if I have an International Plan? Or Should I just cancel my 2 year contract and buy a cell phone in Korea?

For anyone who's been to Korea

Is the iphone 4s a safe buy?

So after much saving and selling some stuff i will be able to in a near future purchase a new iphone. This is due to contracts in my vountry being very stupid and expensive and they simply don't make the phone cheaper ie in the us a new iphone 5s will cost 199 on a contract vs 599 new and i know i'm streching the numbers but it's for demo purposes and here it will get probably one hundred euros from 599 so yeah i don't have that kind of money available for a phone.
I can howecer purchase a 4s which is probably my favourite phone of all times because of the look the feel and of course it's probably one of the best phones ever. However i like to think ahead because i have some knowledge on this stuff and i know it will get ios 8 but what abou nine?
I think it may because it's still being sold on apple us website and with a contract and warranty but again the original release date was in 2011 and the four lasted three years and if we go by that pattern then the 4s useful life will end late this year.
So I don't know! Maybe i should save more and pick up a 5c but again i need input.
So after all this i have two questions:
1 is the iphone 4s still worth it?
2 will it get ios 9?

Sorry for typos as iim writing on my ipad and rather quickly.

Will this add to my 3G data allowance?

On my iPhone 4S on the settings tab where you turn on your 3G there's a button to turn Cellular Data on/off and another button for my 3G. If I only have cellular data on and not 3G will it add to my contract bill because all I have is 100MB so I really don't want to go over and pay more than I already have to so basically if I have cellular data on will it eat away at the 100MB I have?
