I would not mess with the temp sensor on the logic board. I would try a restore. If that does not work then I would look at recycling the phone and getting another 3GS or upgrading to a newer device.

In researching this many people attributed it to faulty batteries. I have tried three different batteries (from the same supplier) and they all do the same thing; it may take minutes or hours, but eventually the warning pops up, and once it does, it pops up more and more frequently.
Does the bad battery idea seem plausible? If so, where can I find a reliable source of batteries I might try? Do quality and price go together, or are they all from the same few factories in China? Thanks.

iPhones are not user servicable.
You have essentially rendered the device useless and Apple will not touch it at this point.

Apple didn't want to touch it in the first place as it is way out of warranty.
Their answer is get a new phone. I have, actually, but I'd like to fix this one as a personal challenge.
All I've done so far is software restores and battery changes.

They would have replaced the battery or the entire device prior to you opening it.
Neither is an option now. Junk the device as you've damaged it.

Do you work for Apple? Which store? I ask because I'd like to find a place with someone willing to fix/replace out of warranty Apple products.
What prompted the original battery replacement was that is swelled up and started pushing the phone appart. An Apple "genius" told me that the phone/battery had reached is useful life and this was to be expected--self destruct mode, I guess.
What has been "damaged" that would bring on the Temp Warning? You sound like you might be some sort of tech; have you seen this and fixed it before?

This is a user to user technical support forum.
The only Apple employees here are the moderators and those with Apple logo's beside their names.
Apple will not touch the device now that you have opened it.
