Should I get an iPod touch?

[Kriminal]

Hi.
I'm thinking about buying an iPod touch. I have the money for it, but need to know if it's worth it. Some things I need to know..

1. Can the 3G be jailbroken without being tethered, or should I go for the 2G?

2. Does it have wifi capabilities?

3. Do you think getting a refurbished one would be risky? It's cheaper.

4. How easy does the screen break? Should I buy a case?

Thanks.

It can, but I would suggest 2G for Jailbreaking.

Yes it does.

I think it would be risky simply because of the unique apple product.

The screen is actually very strong.
