Ah yes, that 79-pound iPhone repair kit to fix a 1.1-ounce battery. The review of it was pretty interesting [0]. It's possible, but it's not exactly what I'd call user serviceable. There are a hojillion kits on Amazon which all include all the necessary tools to take the phone apart - triwing screwdriver, pentalobe screwdriver, impossibly small 00 phillipshead screwdriver, etc - so anyone that can follow youtube directions and has a steady hand can do it. It's just way harder than it needs to be so under the proposed law, they'd have to make it easier.
