Is my new 3gS iPhone jailbreakable...confused

[CoJenKy]

Ok, this is my first time posting on here...so bear with me please

I bought a 3gS iPhone last week...I want to know if it is jailbreakable (before I try and end up destroying it or something..LOL) I have 2 older 2g iphones that I have jailbroken but have heard 3gS are different.

It has version 3.1.3 (7E18)
model # MB716LL
firmware 05.12.01

Can anyone tell me from this information if my iPhone is jailbreakable?

Thank you
