Can I take a deduction on my 2007 income tax return for something that I paid in 2008?

I just paid my state/local 2007 property taxes this month (Jan '08). Can I still take the deduction on my 2007 federal income tax return or do I need to take it on my 2008 return?

1. If you paid in 2008, you itemize in 2008. That's what I'm doing (I'll also be paying 2008's taxes in December).
2. there are few exemptions that allow you to do this. Some retirement investments and some home energy credits, but that's really it.
3. No. The only thing you can do in 2008 and take a deduction on taxes for 2007 is fund an IRA.
4. No, you can take it on your 2008 return but not for 2007.
