Why doesn't my iPhone 4 show ios7 update?

I just heard that iOS 7 is available for iPhone 4/S, and when you go to settings-General- Software update it shows my iOS is up to date which is 6.1.3…
And I just wanted to know why or is it really supported for the iphone4
I know that it lags cause iPhone 4 has a A4 chip not like the 4S which has a A5 chip…

IPhone vibrates before I get text?

When I receive a text message on my iPhone 4S, my phone vibrates around 5 seconds before my phone sends me the alert that I have a message. Usually this happens at the same time. How do I fix this?

Iphone 4 is 1 gig a month enough?

Ok so i'm thinking of getting the iphone 4, the deals perfect and all but there's only one problem. I only get 1 gig for a month. Now all i want to is, how much megabites does facebook, qoohme take to go on it/download it. And also what about downloading games how much megabites does that take. Or what if i connect to a Wi-Fi would that take gig away or what. Really would appreciate if you give me a good explanation for all this. My parents said 1 gig a month is nothing. So is it or isn't it?

I think i love her? How can i win her back or get over her?

Two years ago i started talking to this girl, and there was a real connection between us. We started talking in february, and by the end of august she was one of my best friends. We were more than friends, but not in a relationship. We would always cuddle, kiss on the cheek, once kissed on the lips but she didn't want to go any further as she hadn't kissed anyone before. But it was very obvious that we had strong feelings towards each other. Our friends who we went out with at the time always told us that we should go out and we looked cute together. But we slowly drifted apart from each other after the august 2 years ago. We used to talk all day long, every day on bbm. But we started to talk once a day, then once every other day, etc.until it led to us hardly speaking. When we were hardly speaking, we still said hi and held small talk when we saw each other (which was most mornings on the bus to school) but eventually that stopped and we just ignored each other and listened to our music.

But about three months ago, during p.e (gym class) i had my iPhone on me, and gave it to my friend to hold as he wasn't doing football. But during this time he went on to my Facebook and started to speak to her, and eventually asked her to prom. He told me straight away, and i laughed it off and said something like i don't care. But on my way home, alone, i realised i want to go to prom with her (the answer to what my friend said was obviously a no, as it was strange asking after almost 2 years not speaking), so i started talking to her again over Facebook, and we started texting once we exchanged numbers. But these are the conversations which i missed and i realised my feelings were coming back. I have told her about my feelings and she said she thinks the time has passed and we should just be friends. I have tried everything to get her to fall for me again but nothing has worked. At parties i have got with other girls, and when I'm with them i seem to think i'm over girl 1.

Added (1). But after i'm finished with the other girls, i realise that i still have feelings for girl 1. I don't get on with her new guy friends, they're nerds and really boring + unfunny, but i get on with her girl-friends and i'm kinda close to about 2 of them. Every song about feelings i hear reminds me of her, especially how my sister has been playing Jason Derulo it girl and what if recently. I just want to love her and spend time with her. Can someone give me some advice of wining her back or getting over her.

How to change my tumblr email on the mobile app?

So I forget my tumblr email so I can't log on with my computer. But I can't figure out what email I used or how to find it on the mobile tumblr app. I have the most updated version for iPhone 4S, how can I figure out what my *** email is? It's really frustrating.

What cameras are best for beginner photographers but cheap?

I love taking pictures but the iPhone quality isn't cutting it for me anymore. I wanna be a photographer later on but for now I want to find a camera that's for beginners and cheap. Pictures like on tumblr is what I'm aiming for. That way I can slowly go into editing them but thats later. Great and super affordable! Please and thank you!
If you included where I could find one and or price I'd appreciate it!

Why are internet ads becoming increasingly similar to the pop-ups we all hate?

They give me an X, so you'd think I could click out of them, but instead they just redirect me to another website.

They give me this "Help! Help! Save the Iphone from being flushed down the toilet! And then you win it!" It's annoying as hell, comes with a an annoying toilet flush sound effect, and can't be clicked out of, save for refreshing the page.

I just want to enjoy some internet, maybe I have a virus. I couldn't tell you, because very suspicious looking ads telling me I have a virus, or my PC is about to crash, keep popping up! Why hasn't it crashed yet!

Please, if any of you have dealt with this monstrosity of an annoyance and done away with it, let me know.

Or give me the address of the people who make these dumb ads.either or, thanks.

Iphone 4 won't read the Sim

Recently my iphone broke due to water damage, I fianlly got a new one second hand of a mate free of charge, the phone was orginally on orange but I'm on 3 network, I took it to the store to see if it was unlocked and they checked it and told me it was, he then put my 3 sim into the iphone and told me it wouldn't read it, so I thought it was because maybe it had got wet from my old phone came intact with water due to dropping it down the toilet, when I got home I tried putting the orange sim back into the phone and it wouldn't read it, it would come up with SIM Failiure or invalid sim at the top, I tried my 3 sim back in it and I ggot the same message, iv put my sim into my sisters iphone and it read it fine, so now I'm worried if its a fault or not?
Can some please help me? Can I fix it? Is it the sim, a fault, or just the pphone and settings? Please need help as soon as possible!
