How to get All pictures off iPhone 4? - 2

My iPhone 4 is gettings a little full of pictures ( I have around 850) so I want to upload them all and delete the first 100 or so to make some room. The problem is, the first time I ever plugged my iPhone to the computer, I didn't choose to upload my pictures. The next time I plugged it in, I could only figure out how to get the pictures taken AFTER the date i had plugged it in. Same for the next time. Is there a way to just get every single picture off the iPhone instead of ones taken after I had plugged it in previously?

T mobile dongle how to top up?

My router is broke so we bought a t mobile dongle. Plugged in SIM card then plugged dongle into laptop. Have the receipt with top up number on but when I try to top it up it asks me for a phone number to register, I put my phone number in but it says 'that phone number can't be used for my tmobile please try again' I'm on orange and 3G Internet on iPhone 4, why is this dongle not working? Do I need to be on t mobile Internet in order to use a t mobile dongle? I'm really lost and extremely pissed off about this!

Does the apple warranty cover this?

My friend dropped my iphone 4s and its screen isn't cracked but the graphics card inside of it is messed up. It keeps the phone at a blue screen with stripes of more blue and stuff. The graphics card is literally messed up. If I say I put it to charge and when I picked it up the blue screen was there, will they replace my iphone since I have the warranty?

What does the Iphone 5 warranty cover?

I dropped my iphone 5, but only on the corners and there's visible damage. Recently my lock button has been malfunctioning and only the left side of the button works. I was wondering if they will still replace my phone after this. I've read up on the "issue" and most people with this "issue" say they walked in and walked out the next 5 minutes with a brand new phone. This makes me think will they not replace it if it's my fault that is probably doesn't work.

Added (1). Also if i they will fix it, should i schedule a genius bar appointment or just walk in?

Hot to restore music in iPhone using iTunes?

So I downloaded music on my computer then put them on iTunes then plugged my phone in and out it onto iTunes of my iPhone 5. Now I plugged my phone in, and deleted all the songs in my phone, I had 100 + songs but when I look on my phone from the computer it shows them all but if you press on some of them, it gets a little "!" sign next to it. But on the phone it only shows 40 of them.
