I wasn't really referring to the 'carbon footprint' if thats why you brought cars into it. I was more referring to things like PCBs and batteries, and the chemical processes used in refining these things. Toxic and harmful chemicals appearing in ecosystems they shouldn't... when things like cell phones don't get reprocessed properly.

There are plenty of toxic chemicals in car manufacturing. Hell, cars (particularly old ones) produce these toxic chemicals continuously while you drive them! Smart phones are a hell of a lot less toxic than cars.

As for the comparative benefits, we could argue until the cows come home - both products are insanely useful and life-changing - but if we simply declared them equally useful, that would make phones a better bargain due to the much smaller amounts of toxicity.

And there are not only environmental effects but social too. IEEE Spectrum has an article this month regarding this. Is a good read.

The good news is that services like gazelle, Amazon Buyback, eBay Instant Sale and Verizon Trade-in are making it more likely that old phones get sold and kept in use, instead of rotting in a drawer until they're tossed into the household waste.
