How to delete photos from iPhoto in iPhone 4S?

So when I got my iphone, I thought it would be a good idea to import all my iphoto photos (all 2500 of them) onto my phone.
However, I want to get the new software update, and it won't let me because I don't have enough storage. I have tried almost EVERYTHING to get these darn photos to be deleted, but I can't figure out how to do it.
When I go on itunes, the only thing that comes up under the photos section is just "sync". That's it.

I tried to delete them manually on my phone, but I don't have that "delete" option. (when you open an album, click on the right, and a delete button should come up at the bottom).

How to reduce storage level on my Iphone?

Okay, I'm having issues with the storage on my iphone. I have a very high amount of used storage, but I have no music, and the only apps I have are temple run, facebook, snapchat, and pic stitch. I thought it may be because my messages are taking up too much room so I cleared every conversation in my inbox. I also deleted call history, internet history, cookies, reset the cellular network data, and deleted unnecessary photos, however it still did nothing. My sister has music and way more apps than me but her storage is still lower. By phone is basically empty and it the storage level just won't go down. Do you have any suggestions?

Location Services Disabled on Missing iPhone 4s?

I accidentally left my iPhone 4S in a locker-room yesterday after a tennis match and I didn't think much of it. I thought I would go back and get it the next day because I was going to a sports game. Well, today I went in the locker-room and it wasn't there. I thought I hadn't searched my bag hard enough so I went home and it wasn't there. I tried using 'Find my iPhone' to track it, but it came up with 'Location Services Disabled' with the green dot, meaning that it had been found, but it couldn't show me. I began to freak out as the school hadn't reported any recent phones coming up. It has a three number passcode on it. Please help? Do you think someone might have stolen it/gotten into my phone?

My iPhone has been charging an entire night but won't turn on?

It has water damage but was repaired with minor issues as expected. The last two nights its taken longer and longer for it to charge to turning on. Last night is the worst because its been charging for over 8 hours and hasn't turned on. AND YES the lightning bolt' symbol is on.

Anyone have this prob? I'm worried it will just never turn on again? Have you heard of this happening?

Added (1). Yes I've tried the soft power down holding both buttons doesn't do anything to turn it on

How much would it cost to replace/repair my Iphone 3GS?

With the Iphone 5 coming out this weekend and etc I was wondering how much it would cost when I go to the Apple store to get my 3GS replaced with a 3GS. I'm the lucky one who is not avaiable for an upgrade and warranty went out literally 6 days ago. Figures huh? The phone is stuck on the Apple logo when you turn it on. I've reset it, restored it, recovered it and it still stays on that screen so I'm taking it in tomorrow to get looked out. Just curious to know how bad they are going to screw me over for a phone you can get for 99cents with a new plan these days haha.
