Is there any way to install cracked .ipa or .app files on an unjailbroken 2.1 iphone 3g?

Thanks

ABSOLUTELY not.
It needs to be jailbroken 2.0 iPhone software. The reason for this, is because you need to have a jailbroken iPhone firmware to be able to change the MobileInstallation framework. This is needed to be changed to sync and play the cracked IPA's.
