Windows 7 - [XBOX/PS3] PS3 Prestige Token Glitch for Modern Warfare 3

Call of Duty: Modern Warfare 3 - Unlimited Prestige Token Hack/Glitch
USE AT YOUR OWN RISK!!!


Requirements:
Only 1 Prestige Token
A friend

1: Get a friend to invite you to his party.

2: Once in his/her party go into barracks and go on the 'Unlock gear' then go to perks(I don't know why perks but still...) click the one you want unlocking. DON'T CLICK YES OR NO!

3: The prompt box should be up with the yes and no now get your friend to search for a game. You wont be able to do anything with the YES and NO prompt box because it's glitched up.

4: Once in a pregamed lobby get your friend to back out. You should still have the YES/NO prompt box up. When your friend has backed out you will be back into his/her party, you can then still use the options in the background with the prompt box still up, such as barracks, callsign etc.

5: Go to barracks and click double xp, prompt box will come up, click yes then the other prompt box for the perk will still be there and you will be able to click YES / NO obviously click YES.

6: Because you have 1 prestige token and it has just unlocked two things it will take two prestige tokens off, the one you actually have and an imaginary one, it will then set you to -1 prestige tokens and you can just buy anything for free, without needing your friend it will keep going down when you buy stuff like -1, -2 etc.

Make sure you have ONLY 1 TOKEN, because going into a negative value is what allows this glitch to work.
Once in negative, you can use as many tokens as you want on your own.
