When you say jumpering the pads with fine wire, do you mean recreating the loops and soldering to the trace?

I'm a bit confused about the pads though, from what I've read about this problem, they may connect to internal layers within the holes. In which case, how do you know? This is what I meant about filling the holes with solder (as they were originally) to make all the connections with the inner layers. Any clarification of how this works would be appreciated.

I'll take some pictures of this when I get the new iPhone in June and can take some decent pictures.
