I have a Galaxy 4s its with T-Mobile, but I dropped it and the screen turned permanently black and it still works but I can't see nothing and can only make a call when i'm in my car using the steering wheel. Can I trade back to T-Mobile for a iphone 5?

I was wondering if i could do some type of trade in value or maybe sell my phone back to them and just pay the difference for the new phone. Any respond will help thanls xoxox

Any advice about getting a good lifespan out of my iPhone battery?

I've had an iPhone 5 for almost a year and I'm really worried I've ruined the battery. Nothing odd has happened to it but I just think I charged it overnight one too many times so I'd like to… Well reverse the damage.

I know to run it all the way down to 0 (I have just always done that) and I charge it to 100% but I'm worried I ruined the battery bc I would charge overnight. Also i use about 80-90% in a day sending a lot of texts ha, using the Internet, maybe an app or two, and then listening to music for probably 3 hours.

Question: What things do you do to protect your battery's life? Any advice welcome but hey the more expertise the better.

Follow-up question: Given that sort of activity is the battery's drainage (80-90) unusual? Or is my battery okay?

Is the iPhone 5c cool or same as 4s?

I'm 13 and my moms old phone broke so she was going to upgrade my iPhone 4S to a 5c or 5s or whatever came out and then she'd keep my own phone.

Before you say anything rude about me being spoiled, I'm not. My family is an Apple family. We just like their products. I got my iphone for my 13th birthday and I turn 14 in two months.

One of the reasons I don't want to upgrade is because I hate having more than someone else. I hate bragging. Sometimes it'll sound like I'm bragging then someone confronts me and I start crying because I feel bad.-.

Another reason is because I just bought myself a new case and I absolutely love it and it'll take a while to find another minion 5c case lol

Does the iPhone 5c/s have any better features or is it the same?

I can't turn on the Wi-Fi on my iPhone 4S?

It's greyed out and I can't turn it back on! I tried everything resetting network settings
and restoring iPhone but nothing works! I'm currently running iOS 6.1.3. The iPhone is a sprint one.

Is it better to buy the iPhone 5S with or without a contract?

*benefits*
On one hand, you pay less with a contract.
On the other hand, if you don't do the 2 year contract, you can upgrade to the next iPhone when it comes out (most likely the iPhone 6).

*downsides*
With the two year contract, you can't upgrade until your contract is up.
Without, you pay about 3-4 times as much

*by the way, I'm eligible for an upgrade*

Added (1). @Michael I would do that, but I have an iPhone 4. I think it's about time I upgrade my phone, lol. It's kind of outdated…
