Soldered a jumper to a circuit board upside down

And I've had no luck in re-heating the solder and pulling the jumper header out. The problem is that the pins sticking out of the board are now too short to hold the jumper, which is needed to complete the circuit.
What I'm wondering is will the circuit work just the same if I keep the header installed upside down and cut a jumper down in size to fit over the pins?
If not, what is the best way for me to go about fixing this?

as long as it completes the circuit, it should be fine. why can't you take it off?

I tried reheating the solder and pulling the piece out with pliers at the same time but it just won't move, and I'm worried that I might damage that area of the circuit board by heating it for too long. I also hope I haven't made the solder go bad by applying heat to it for too long.

Get some copper braid (from any radio shack). Heat the solder up and it will wick into the copper braid like water into a sponge. (Cut the used bit of braid off the roll and toss it when done.)

I have a neat iron used for just such problems, and to disassemble boards. It is a normal iron, but the tip is hollow and is connected by a tube to rubber bulb.
Place the iron on the joint with the bulb squezed, and realese it once the solder melts. Then you can sqeze it again forcefully into a moist sponge to expell the solder. Very usefull i have found, both for scrounging parts or boards, or well fixing mistakes.

I'm having trouble finding copper braid at hardware stores, and Radio Shack (called The Source now, at least here) doesn't carry, but there's more places I can try.
A friend told me it's the CB is messy to work with and doesn't do too good a job, that instead I should go for a desoldering suction gun. I'd rather just get some CB than buy a desoldering gun, but is it really messy/ineffective stuff to use?

Perhaps if you don't know what you are doing. *shrug*
You can get a desolder pump that isn't built into the iron fairly cheap. Do a google image search on "desolder pump" for zillions of pictures of what I am talking about. Shouldn't cost more than ten bucks or so. Basically, spring loaded suction device. You push in on the plunger until it locks. Heat up the solder until it melts, put the nozzle next to the liquid solder, and hit the button.
