Well, i have an iPhone 3G (normal, SIM free) with:
- iOS 3.1.3 (restore with TinyUmbrella from 4.2.1 to 3.1.3)
- Bootloader: 5.09 [G2M3S2]
- Baseband: ICE-05.15.04
- iPhone SIM-free
- i do NOT have any SHSH of any firmware
can i downgrade this phone from 3.1.3 to 2.x (2.0 possible) with DFU (ireb) -> iTunes -> TinyUmbrella ( exit recovery)
P.S. I do not have any shsh so could you please help me? Is it possible, also, jailbreak it with ios 2.x firmware ? Thanks

You will need a Mac to do it I believe. Not much will work with 2.X, most apps won't even install on it, really isn't worth the trouble. 3.1.3 I would say is the best firmware in terms of speed and compatibility.
Edit: Did find these if you are dead set on doing it:
