How to track an Iphone online?

I recently bought an Iphone but I'm wondering if there's any way to track it's location incase it is stolen. For example, is there an app I can download that will auto start when the Iphone is turned on and I can track online at home via GPS or something?

Car Dashboard Overheating? Ford Fiesta Ghia?

I have a Ford Fiesta Ghia, and it gets So hot in the car when you drive, but its heat inside the car, as if you have the heating on, even when the heating is OFF.

But when you try to put cold air on, it still comes out really hot.

The dashboard gets that hot that it shorted out my iphone which was on it, and the iphone came up with temperature warning, "iphone must cool down before use!"

I'm sure this is why it is costing me a lot more in petrol too, it's as if the car is permanently "heating on"

What could the problem be?
Is it something that can be easily fixed, and can anyone give an approx price?

Incidentally neither the cigarette lighter nor internal light work, but the fuses have not gone

Why has my iphone stopped charging?

Is it pointless to have data on your iPhone and iPad at the same time?

Would it be completely pointless to have a data plan on both your iPhone and your iPad?

A little background information:

My T-Mobile contract expires soon, I plan on switching to Verizon. I haven't upgraded my phone since 2008, with this said, I would also purchase the iPhone 4S device under contract for $100. I'm also getting an iPad 4th gen. For Christmas.

My question is, wouldn't it be rather pointless for me to get a data plan on both my iPhone and my iPad? The only time I would really use wireless internet in public is on my train ride commute - which would be more appropriate to use my iPad to browse the web, go on YouTube, watch movies, or even listen to music.

The only problem is that using internet on my iPad would essentially be less portable than a phone. Meaning, I couldn't go on the internet as many places as I could if I had internet on my phone.

My question is: would I be able to tether internet from my iPad to my iPhone and vice versa? For example, I got a data plan on my iPad, could I tether the internet to my iPhone and use the internet on it?

or

I got a data plan on my iPhone, could I tether the internet from my phone to my iPad and use internet on my iPad? (with a jailbroken iPhone 4S)?

Added (1). Okay, thanks for the advice, guys. As a follow up question - does Verizon offer the wireless hotspot option? Or is that limited to AT&T?

Why does my iPhone 4S battery die so fast?

My iPhone won't synchronize

I have an iPhone 4S 16gb.
I have all updates and much space for more music.

First it would not synchronize, so I thought I had to delete some songs to make space. I deleted it and synchronized it again. The songs "went away", but it still won't put in the new songs. They are still gray.

Any ideas!
I'm not from america/england so I hope you understand.

Did my iphone 3gs battery die?

I have an iphone 3gs I want to get hooked up for my little sister to use as an iPod touch. I woke up one day, and the phone wouldnt turn back on. It wasn't plugged in or hot, so I'm thinking the battery died? Is there anyway to know if its the battery. I could just get that replaces.
If I plug it into the computer or a charger nothing happens with it.
I think it's the battery, is there anyway to tell for sure?
