Doublecheck firewall (though not selective).
How long has this been a situation for, did it begin with the 8300 or did you get some normal operation afterwards? Roughly how many networks have originated SMS intended for your wife?
If you haven't done so already then hard reset, if this fails to resolve then force contact with your home location register, by placing and removing diverts/bars or similar. If you still have a problem then one of the originators of the unreceived SMS need to get in touch with their network and request they confirm failure reason. Using an sri_sm (send routing information for short message) the originating network will be able to confim that the responding element is on the correct destination network and what response it's getting from that element regarding the Subscriber.
There is nothing on the device itself which gives a monkey's where an SMS comes from (network wise) so I'm not surprised TMO found nowt ;)
At a guess I would say that either Number Portability? SMS routing is screwed, TMO are providing an invalid response to sri_sm or the Subscriptions has a stuck "mobile not reachable flag" set and they deliver their own SMS as "priority".
