Can I install 3.0 apps on 2.2.1?

[NSK123]

I currently have a jailbroken 2.2.1 Iphone 3G and I wanted to install the MobileNavigator Europe app, Can I do this on the 2.2.1 firmware?

I don't really want to update to 3.0 yet because of the lack of items from cydia which haven't been ported to the 3.0 firmware yet... Winterboard etc..

I wasn't able to install 2.2.1 apps with 2.2, so I am guessing no.

Seriously, what do you think? If it was made for 3.0 it works only with 3.0. You may have noticed that 2.2.1 apps don't work with 2.2.
