Possible spoilers, but a variety of ways to cheat...
For those of you that want to make 2 game saves, you can add an item cloning glitch that was discovered by a guy at gamefaqs yesterday morning to your money glitch (works on black soul gems and many, many other things). I've also used enchanted gear to achieve a constant chameleon effect, basicly "god mode" you can hit an enemy and it won't strike back, but it is good for stealing stuff. In testing it out, I found that I can kill a guard in front of another guard and nothing happens, but if you kill a mage you still get kicked out. Comine the chaeleon suit w/ the skeleton key w/ the money glictch, w/ the item glitch, w/ my grand black soul gems, I can do whatever I want (I can always take off my chameleon suit or go back to normal lock picks)

Easier way of doing it that was posted on the official elderscrolls forum
1. Draw back bow
2. Go to item menu w/ bow still drawn
3. "unequip the arrows that are equipped" (it will say that you can't)
4. select a different item category than weapons
5. Then you can go back to weapons or to another item category
6. Find the item you want to clone, and drop it
7. Leave the menu and the items should go flying on the ground
Some important notes
1.the number of clones of an item depends on the number of arrows (If you orginally had 15 arrows then you will clone 15 black soul gems that will go flying all over the ground)
2. Be careful with number of items you clone, the game can slow down to a crawl if you had 200 arrows and you clone one of the stones from the oblivion gates.
3. It does work on an item more than once
