How much is my iPhone 4 worth if the battery needs replacing?

I've had an iPhone 4 which I think is 16gb for nearly 2 years which I had bought for me second hand in excellent condition. I'm looking to sell it as the battery has become useless and needs to constantly be on charge for it to work and I'd rather upgrade to an iPhone 5 instead of pay out for the replacement. Other than the battery needing replacing it is still in good condition with just very light marks of use. How much should I be selling it for? Don't have a clue!

IPhones IMessage isn't working?

If I'm texting someone who doesn't have an iphone my texts will send perfectly fine but if I text someone with an IPhone and use IMessage it will say my message delivered and then a couple seconds later say "Not Delivered" under the message and I have to send it as a text but that person won't even get that. I can still get texts from people using IMessage but not send them. I've tried turning my phone on and off and disconnecting to Wi-Fi and then connecting to it again, neither worked.

What is wrong with my laptop? - 1

I bought Arma 2: Combined Operations off Amazon. I also bought a 32 GB USB drive. I have to download the game, but it is saying I have 120+ hours remaining. I have Wind Stream. There are 2 iPhone 4's, a desktop, and this laptop on the wireless box. When I try to download the game I turn off the desktop, but that still doesn't seem to help. I keep nothing open on the computer except for the download itself. Anyone have any ideas what to do? I have a Dell Intel laptop with Windows 7. This is really annoying me. Please give me any ideas as to make it faster. Is it my internet, my laptop, or both?

Keep breaking iPhone charges?

I've bought 5 chargers (5c) from five below and I break then within three days and I have no idea why, I don't abuse them or anything. WHERE SHOULD I BUY NEW ONES?

What iPhone 5c should I get?

I want to get an iPhone 5c, but I don't know which color and case I should get. I want one that is good quality, and first my personality. I don't want scratches or dirt to show up easily

Most people would describe me as a sweet, shy, smart girl. But once you get to know me, I'm really funny and weird. I love to laugh, and hang out with my friends. I love art, especially drawing. I also have an obsession with giraffes and turtles. Food is cool to. I don't really stand out and I'm soft spoken. But I do want to be noticed. My favorite color is mint green or mint turquoise.

I like the yellow phone, but none of the cases look as good with it. The blue one is cool cause it looks good with the pink case

Please answer what case you think is best for me. Thanks! Winner gets an easy 10points!

Added (1). The green one isn't exactly my favorite

Added (2). Never mind I like the green one
