My iPhone 4 is freaking out?

So I've had this phone since July of 2012 and my upgrade is this year. I have to wait for my upgrade to get a new phone but my 4 is spazzing. It makes the keyboard disappear at random times, the keyboard has missing letters at times, I can't see my messages unless someone texts me, all my apps crash all the time, and the phone freezes constantly. I don't know what to do and this is getting annoying.

Why won't my iPhone 5S connect to the Wi-Fi?

I'm in Spain for my Easter holidays and staying in our apartment. We have a Telefonica Wi-Fi box which connects well.

Recently I've been trying to connect my iphone 5S to the Wi-Fi box but it doesn't recognise it or give it a small tick that it's connected. I know it's connected as my iPad is working fine.

The mobile network I'm on is EE but in Spain it's 'Orange' . It's really annoying me as I want to go on social networking sites eg facebook or twitter.

Does anyone know what I can do?

IPhone 4s need to be backed up while on recovery mode?

I have an iphone 4s ios 7.02 and the phone only turns on when connected to the wall but when connected to a computer it goes to the apple loo then shuts off then to a charging logo. I can't backup the stuff when it turns on when plugged to the wall because there's a Wi-Fi problem where i can't connect to Wi-Fi and can't connect to a 3g network. So i don't have a backup of it. I need to back up the stuff without restoring or deleting it. Plus i have tried to restore but gives me error: 4031 or something like that. Its a hopeless case but i know there's a way i just want to connect it to the computer back it up and throw this phone away unless if there's another way but i don't want to replace the battery or anything

Why does everyone have iPhones these days?

It seems that everywhere I look, every girl my age (14) or older, plus kids 7-12 years old, elderly, adults, everyone has it.

It don't get it, really. It's just a phone, and there are phones out there like Androids that are much better in many aspects.

Sometimes, I want to cave in and get an iPhone because I actually like the IOS 7 display and the design seems to be attractive. And not only that, but seeing all my friends have it makes me feel a little left out.

I do have an iPod Touch 4G, but I don't necessarily use it very much.

So, anyways, why does everyone have them?
