Is it reasonable to ask $300 for my iphone?

I have an iphone5. It's black and has 16 GB. I also have the charger, the box it came in, and a defender otterbox. So is it reasonable to ask $300? I've only had it for a year. And I don't have any real damage to it. Also it's on sprint.

Why does my daily booster wheel not work in Candy Crush?

The daily Booster wheel icon is present and when I click on it the wheel launches, but the wheel is dark grey and will not spin. When I close the wheel and try to launch it again it tells me to come back later for another spin. The game is on my iPhone and is not linked to my Facebook, nor do I want it to be. Does anyone know why this is happening?

How to remove iCloud from an iPhone 5c?

I recently bought this iPhone 5c from a guy. I'm guessing it wasn't reset or removed but it said it was locked to someone's iCloud and now I can't activate the phone, does anyone have any suggestions on what I can do?

How to transfer messages to new iPhone?

I recently got a new iPhone 5. It had a broken screen so I wanted to wait to fix it before transferring from my iPhone 4. In this time to get it fixed, I used the iPhone 5 for iMessage and the iPhone 4 for actual text messages since the iPhone 5 was obviously not capable of doing that at the time. Now that I have the screen fixed, is there a way to keep the iMessages on the iPhone 5 while adding on the text messages from the iPhone 4? I know I can do a restore from backup, but that doesn't get the combination of both phones' messages. Does anyone know a way to do this?

Does texting on iPhones use data?

I just got an iPhone 5c a couple of days ago after having a "dumb phone" for two years. Today I noticed that every time my 3G was turned off and I didn't have Wi-Fi my texts took a long time to send, or they didn't send at all. I'm aware that iMessages only work with Wi-Fi, but what about regular texting? Does regular texting need/use data? This probably makes me sounds really stupid. I'm sorry

If I buy an iPhone off of someone do we need the same carrier?

I'm interested in buying an iPhone off of a friend of mine but she has Verizon while I use AT&T so I was wondering if this would cause a problem in any way. Can I switch the phone from Verizon to AT&T or do I need to purchase a phone in which was initially from AT&T? What I'm trying to say is, will purchasing a phone off of someone with a different cell phone company than my own make the phone unusable to me?
