iPhone 3G Questions

[MacGeek7]

So I had a 3G iPhone up until a couple months ago when I sold but now that Apple has dropped the price to $99 I started thinking about re-purchasing it.

My questions are this,
If I get the iPhone 3G (again) how long do I have to cancel the contract before the ETF applies? I heard if it was canceled within 30 days it doesn't apply, is that true?

Would you recommended jailbreaking/unlocking it? If so, which tools would you use? Can I even unlock a 3G iPhone in the U.S.?

Thanks for the input!

and yes, I did search using MRoogle but I couldn't find the answers I was looking for

First off, if you did use MRoogle, you would have found your answers.

Secondly, ETF don't apply within the first 30 days because you have to return your phone if you cancel within the first 30 days.

Again, use MRoogle, but this time actually use it.
