yup, i just flashed another tsop for a friend, and i left the jumpers unbridged.
in this case, i didn't even solder. all i did was strip a piece of wire, cut it in to a really small piece, bent it, then stuck it inbetween the two points to be bridged and went over it w/ electrical tape and voila!
now that i know how to solder the right way, it's a piece of cake, but nothing beats this. it is a hassle to get right though.
