Making use of the new CVS accessiblity, you can find updated php.spec and patch files at:
http://cvs.fedora.redhat.com/viewcvs/rpms/php/FC-3/
With these, you can roll your own 4.3.10 RPMs if you can't wait for them to be officially released. Do note that these would be fully unsupported, etc and you do so at your own risk and all of that other disclaimer stuff. You would certainly still be wise to update to the officially blessed RH packages once they are released in any event.
Meanwhile, I figured I'd take the leap and move to the 5.0 branch. Alas, I've been unable to get the new 5.0.3 tarball to build using the old 5.0.2 specfile:
<https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=143101>
I don't see a 5.0.3 spec file in CVS yet:
<http://cvs.fedora.redhat.com/viewcvs/rpms/php/devel/>
