Is texting or calling from iPhone to iPhone free if you're in a different country?

I live in the US And I'm going to Sydney, Australia for 3 weeks in a little while but I'll only be 17 when I go with one of my friends and I wanted to make sure I could communicate with my mom. There aren't many hotels I can find with free Wi-Fi or even Wi-Fi in general. The hotel we're probably going to stay in only offers wired. Both my mom and I have iPhone's so if we text or call on the cell phone data (I have Verizon) will my phone bill price be crazy high?

Why does my iPhone 4 battery run out so quickly?

I have an iPhone 4 running IOS 7, and my battery runs or way to quickly. I did all the things in the settings that are supposed to help battery life but they didn't work. I also always close out of my apps. Is it just IOS 7, or do I need a new battery. It runs out at a rate of about 1%/per one and a half minutes on usage, and 10%/hr on standby.

How to get my iphone to charge?

I have an iphone 4 and the original charger that was with it. For some reason, it won't charge. I've tried resetting it, using different charges, using different outlets, cleaning the part where you put the plug in, connecting it to my mac, and clearing the memory. None of that has done anything. Whenever i plug it in it says it doesn't reaconize its plugged in and it doesn't charge.

P.S
here are a few things that may have affected it:
-I got back from a few days ago and it when through airport security
-I dropped it pretty hard on pavement
-A month ago it froze completly while skiing
-yessterday i "synced" it to my mac to upload images

My iPhone screen is not responding? - 1

It was cracked before very badly and I'm not sure if something got behind the screen because of how bad its cracked or if it's because of the cracks themselves or something completely different. Also, the day it did that I played music in the bathroom while showering and it was very steamy bc no fan in there, and it was slightly wet. Is that why?

What does Retina Display really mean?

I was told that retina display on the iPhone means that the screen is so HD the the human eye can't detect pixels…

However, I just saw a commercial for the samsung galaxy note. And it said it had a higher resolution screen than the iPhone. Why does it matter if the Samsung phone has more pixels than the iPhone when you can't even SEE the pixels on the iPhone? If you can't see the pixels on the iPhone, the screen on the Samsung is going to look exactly the same as the iPhone, right? What the heck?

RunKeeper or Nike + Running App?

So, I have both of these apps that I use for running and I love them both. However, I don't need both and can't use at the same time and I really just need one app to track my progress. I'm an avid runner and I was just wondering which do you all prefer? Also, on either, is there an option to manually put in your information from a run? Like time, distance, etc. I don't like to run with my Iphone because I'm afraid of breaking it or sweating on it. I have an ipod touch though that I usually run with, but the gps doesn't work on it where I live. I'm just looking for running suggestions? I need something to track my distance and time for me to see how I improve.
