Can I check in with my iPhone for southwest airline?

I have a flight to Dallas from NY this Friday & I know you're suppose to check in 24 hours before the flight, however I will be at work exactly 24 hours before it & I really don't want any bad seats… So I prefer to do it as soon as they allow us. I have an iPhone 6+. Iv heard there's a south west app as well from where you can check in but can I print my boarding pass at home later on then? Or do I show them the boarding pass from my phone at the airport? Never flew with south west before

Iphone 5 Touch Screen Unresponsive?

Over the past few days my Iphone 5 touchscreen has been freezing. It goes unresponsive and sometimes comes back after a few mins. Usually though I turn off the phone and then turn it back on and it's still unresponsive. I then go into siri and ask him to open an app. The phone is usually fine then until it does it agin 15 mins later. Sometimes I can go over two hours without this happening. But then my phone died and when it turned back on the screen was frozen. I can't use my siri technique because it is not connected to the internet. I can't currently get into my phone for the past hour. I try hard reseting it like 10 times and it will not work. I also tried to plug it into my mac but it will not connect because the iphone is locked. I got this phone secondhand from my parent. I got it last november.

Why does my iPhone go through so much data in a few days?

I have an iPhone 5, which is running iOS 9.1, and I seem to be going through 1gb of data in just less than a week. The only Internet browsing I do on the phone is a bit of Facebook each day (I also upload pictures to Facebook from time to time), and a few Google searches each day.
