Can I use my old iPhone as a Motorcycle GPS locator?

I have an extra iPhone 3GS from AT&T. I'd like to install it inside my motorcycle as an economical DIY "LoJack." I don't know how viable an option this is, but can anyone give me some possible insight?

1. Could i use a prepaid microsim to solely use a GPS locator App?
2. How would I set up a prepaid microsim on my AT&T iPhone?
3. How much would this cost per year?

I plan to install the phone under the seat, wire it to the battery, disguised as an OEM. Gimme your thoughts and thanks!

Will iTunes wipe my whole iPhone data away if I re-sync on a repaired PC?

Last time my PC ran into some problem and got it repaired, and of course my PC data was gone. So since then, I don't really sync iPhone. But now I want to sync some songs to it, and I wonder if iTunes will think that my iPhone has already been synced with ANOTHER PC, then it could start wiping my iPhone data.

If you guys know any solutions to this, thank you very much. MediaMonkey is useless to me now, as it couldn't even detect my iPhone. Thanks!

Added (1). Wait, I've seen on the internet that iTunes can only be synced with 1 device. That time I synced with iPhone (and its still find) and for some random reasons, my iTunes is messed up, so I reinstall, but it turns out iTunes kept asking me to create a new iTunes library even though I've already created.

Added (2). *still fine

I broke my IPhone screen, What can I do about it?

I don't have any money is the problem… So… What do I do? Can I take pieces of glass out, until the screen is clear, then use that screen, or what? Leave it? What do you do when you break an IPhone screen? If anyone wants to suggest ways to pay for it, that would be cool too.

How to get a refund from itunes?

The other day I tried to purchase an episode from the game app The Walking Dead for the iphone. I put in my password for purchase and was charged, but never received the episode. I emailed the creators of the game already but they said I need to talk to itunes for a refund. Does anyone know if there's an email address to contact them at?
