It's much more accurate than that even now. Cell phone triangulation can get you to with a few feet if there is enough tower density. You'd only be 100s of feet off if you were out in a rural area.

If it's someone like a mod on CP that can only see your IP address then no, they're lucky if they can track your location down to a 50 or 100 mile radius of your true location. As far as your apps and location finder they do user more sophisticated methods than a simple IP lookup so yes they'll be able to pinpoint about the same as your cell phone provider.
I'm not quiet the hard core techie I once was but I'm pretty sure this is still the rule of thumb.

Yep, you got it basically right but IP geolocation has gotten LOADS better in the last 2-3 years. I'd say it's more like 5-10 miles now. Of course that's for home services. For cell phones it gets a bit trickier and the accuracy varies by region quit a bit... but it'll still get you in the right city or damn close most times.
(I do a ton of geolocation work for clients dealing with google maps and google location autocomplete fields)
