How does iphone typing indicator work?

When texting, an iPhone user can tell when the other person is typing. Is that only with iPhone users? In other words, can an iPhone user know when an android user is texting/typing back to a text message?

Anyone use a Password Vault app?

I've downloaded a like a Password Vault App for my iPhone i'd like to use but got a couple questions.

This app is the one where you have a main master password and once logged in you can use the password generator to make really secure passwords and store all your importnant information. I like it because I can generate truly complex passwords and I have all my important info in one app.

The thing is, I feel vulnerable if I have all this information on my iPhone, if I lose it I'm screwed. There's, for security reasons, no online backup and the only backup is a local one on itunes/my computer (which I think is only accesible if I transfewr to my iPhone, I can't read it from the computer)

So for those of you that do use this, how do you deal with this?

Do you keep another copy somewhere else or write it down or something?

Again, I love that I have all my files there and I can have complex passwords and security questions, but I really don't know what I'd do if I need to login to my bank lets say and my iPhone breaks or is stolen, then I just lost all my passwords for everything.

How to fix my Iphone playing at high volumes with my car stereo?

I recently just put a new stereo in my car. It has an auxiliary port which i tried with my Iphone 4.It will work until i put the volume past a certain level. Then it will kind of skip the music. It will be silent for a second then start playing and so on. This worried me until my friend with an Iphone 3GS can play music on it perfectly fine. It is a new auxiliary cable and everything also. I checked my Iphones volume limit in the settings also. I can't find what's wrong. Please help!

Added (1). UPDATE---
I plugged my nano in and starting playing songs off it. The music library did the same thing, but the when i put it to the radio it will work perfectly fine. I can play it as loud as I want. How do I make the songs the same as the radio?
