Help Iphone 4 cracked need new model?

I've had my iPhone 4 for about 2 years, and while on the phone, someone bumped me and it when flying. Had a case on, but the screen was exposed because it landed on the corner of a sidewalk. Can I trade it in for the 5 or 5c, or does it have to be the same model? I traded it in once already because the phone was defective (The lock button was stuck), and they gave me a new one no charge. Am i out of trade in's or should I still be able to?

Cool little things to buy online?

I want to buy cool things online. Like simple little things that people will be like "wow, I didn't know that existed!"
I already bought a portable charger for an iPhone online. I bought water balls that look like little seeds and if you soak them in water they grow into really big bubbles and you can use them in place of soil. And I bought marimo algae balls that you put in water and they grow into fuzzy green spheres as they clean the bowl of algae. Just cheap little trinket things like that! I'm an eBay-addict, so I will buy anything on there if you tell me about it!

ITunes deleted some of my songs after I plugged my iPhone in?

When I tried to download my iPhone songs onto my new computer's iTunes account, it deleted about 240 songs and left me 27. I don't know what happened. When I logged out and tried to log back on, the 27 songs were still on my iTunes but they rest of my 240 some songs were gone.

Forgot ipones password, now its disabled?

My cousin had locked his iphone and forgotton the password. He gave it to me to fix it but i do not know how. I read that we need to hold the power key and home key at the same time, but when i do so, it states "Itunes can't connect to iphone because it is locked with a passcode. You must enter the passcode before it can be used in itunes. Whenever i turn the phone on, i can't put in a passcode since its locked. Then i click ok, and then it says "Itunes has detected an iphone in recovery mode. You must restore this Iphone before it can be used with Itunes. I don't know what else to do, so i need help on how to get it back to normal… That is, if i'm able to.

How to block anonymous calls on iPhone?

Last night, I received a harassing phone call from an unknown number. It literally says "unknown caller" as the caller ID. I tried googling on how to do this, but I only got how to block callers in which the number is known. How can I make it so that calls without caller ID shown can't come through to my iPhone 4S?

Blurry vision, floaters etc?

Hi. I have really bad eyesight but don't wear glasses (even though I have 4 pairs lying around). I'm supposed to wear them when I'm looking at stuff far away like driving but I'm only 15 so don't drive. I get lots of floaters so I'm wondering if that has something to do with my poor eyesight. My vision is so bad I literally have to be 15cm away from my iphone to see the screen and can't see anything in school!

App for making and categorizing notes?

I'm a student at IT and need a clean way to make a database of equations for my math and electronics classes. Ideally I would like to be able to handwrite the equation and have it convert to text version, and store numerous equations for easy referencing. I have found apps that do just the handwriting but I can't save them to look up later, or I can't put them in a category. I'm new to iPhone and iPad and trying to sort through the hundreds of apps is giving me a headache. Hopefully someone out there knows of one I can use. Thanks for any help.

Added (1). Edit: fair enough HoovR, more than likely it'll be just a note taking app with handwriting in it. Even if I have to write the formulas in an odd way I just need to be able to save and categorize.

Added (2). Edit2: after hours of searching and sore eyes I found exactly what I need. For anyone else needing this type of app for whatever reason it's called TopNotes Pro. It lets me create separate notebooks and handwrite what I need to save in each one for quick and easy referencing later.
