How to reset my dead iphone 4?

Charging port broke. It's dead.
I want to sell it, but I don't want whoever gets it back up to have access to all my old pictures, emails, texts, (ESPECIALLY PICTURES!) Lol.who knows what i still have on there? And some people are evil, will go out of their way to embarass you instead of just deleting it all so i don't trust it. I did have a passcode lock on it though. So is there anything i can do?

App like audacity for iphone?

Basically I need an app for ios (iPod touch, iPhone, iPad) that can let you record over yourself multiple times like audacity. I don't need any of the other effects though they would be nice, but i basically need it just so you can record multiple tracks that can be played at the same time. I kind of need it to be free as well.

Iphone 4S is connected to Wi-Fi but won't load pages?

It only started today, i woke up and i had a bunch of problems. My power button is completely jammed and now this. Worst thing is, i have no warranty because it was a present and the gifters didn't give me any proof of purchase or anything >.< It says its connected. I tried resetting the network settings like the apple support suggested but nothing changed. I can't load a single page on safari or google chrome, but i can if i'm just using my 3G. Any suggestions?

I dropped my iPhone 5 and now the screen is weird and not working?

I dropped my 2 month old iPhone 5 on the floor yesterday and as soon as it happened the bottom of the screen has little white squares along the bottom and the screen will not work at all, the home Button and lock button both work and I have tried holding them both down and turning it back on but it has not worked, none of the buttons on the screen work when it's on so I can't unlock the slide button to get onto the phone.

Any suggestions would be greatly appreciated, I would rather not take it to the apple store and have them replace it as I have not backed it up and don't have the money to
Replace it.

IPhone 5 stuck Searching for Service after dropping in water?

Yesterday I dropped my iPhone in the water and had it on rice for the past 24 hours. Today I took it out and turned it on and it works! Now the only problem is that where the cellular service bars usually are, it just says "searching". I've tried taking out the sim card and using computer air cleaner to clear out the slot, I tried resetting it, and it's still stuck on "searching". Wi-Fi still works. What can I do?
