Texting app between different countries?

So I'm going to Europe for 3 weeks with a group of students that I don't know. I need an app for my iPhone that lets me texts my friends and family in america for free. Also it can't be something like kik that has to be on a smart phone. I need something that people can receive on regular phones as well.
so.
-has to be free
-has to be able to send messages between smart phones and regular phones
-and has to send them from europe to the united states

Thank y'all!

What are your opinions on the upcoming iOS 7 from apple?

For those that it applies too- (iPhone owners) what are your thoughts or opinions on the new iOS software for the iPhone and iPod Touch coming this fall? You can see it on apple.com, or check out what the home screen will look like here:

Please leave your opinions below! I'm curious because I personally don't like it at all, it's too simple and childish, and I really like the iphone the way it is now.

2005 Honda Civic or 2002 Toyota Corolla?

I'm turning 16 soon and i can't decide which car i should get. I'm deciding between a 2005 Honda Civic LX or EX and a 2002 Toyota Corolla LE (don't like the look of 2003 up). I want power windows, but don't care too much for the radio because i'm getting a new one that has an AUX input for my iPhone anyways.

Which car would be better in all aspects? Any additional info for either car is highly appreciated!

My iPhone is doing weird things

So lately, whenever I try to tweet with emojis, it won't send saying there's a "connection problem" but then I figured out when I take the emojis out of the tweet, it sends.
Also my phone won't let me update my apps. Only because for some reason, when it asks for my apple id and password, it already has my id entered in there, but only part of my email and leaves out the "@yahoo.com" part, which is the only way it will work.
Can someone please tell me how to fix both of these problems?
