So here's the case, my iPhone is not responding at all when you plug it in, doesn't even charge. It does turn on and works fine, it's just the dock port that doesn't work. It has been unlocked with anySIM 1.1 and I've taken everything out to make it look like it was only activated. Using it with T-mobile and never activated with AT&T.

Is there any chance I can get this exchanged if I send it in? I don't think they'll be able to check much if the dock port doesn't work...

By dock port you mean the 30-pin iPod connector?. If so, then you need to take it to the store and show it to them "on the spot" how it fails to charge. Don't forget to de-activate it before taking it in.

try it on another computer first

and try forcing a restore by holding home when off and joining to pc

many people get this problem , search more for a solution

Could you charge it from the wall plug?

If so, you may try to put the correct lockdownd file into /usr/bin/libexex
It will work again.

You will get this problem if you run pacay after unlocked.
Just replace the lockdownd file with the corrected one.
