Rpm -i is used mainly for installing kernel related packages. Rpm -U 
will install as well as upgrade a package. The option rpm F will only 
freshen packages that you have installed on your system already.

-i for kernel
-U to install or upgrade
-F to only upgrade a package

Rpm is a great program and has very many handy features to keep your 
system in the best order possible. I even corrected my system after 
stupidly upgrading from a gnome-terminal via yum upgrade. (knew better)

--replacpkgs --replacfiles --justdb --allmatches -qaV are amongst the 
features I use frequently.
