Here is the first MW3 Aimbot release to come from the developer forums. As you can see from the video this is still in very early beta stages so this will be a public release for now until any problems are fixed.
For the XBOX 360 this is a SVG/Overflow hack so simply a case of transferring the downloaded SVG (Save Game) hack file to your console to activate the cheat. PS3 aimbot is still in development as it is very difficult to access the game code with it requiring FW 3.72. Some developers now have the PS3 True Blue dongle in hand so hopefully the PS3 release will be soon.
As for this version, all credit must go to forum member C0d3D34TH for the submission.
Heres what he has to say about the release

How to host a modified lobby in MW3 (9999 XP Rank Boosting)
Use a hacked/modded lobby to rank up fast on Modern Warfare 3. All player receive 9999 XP per kill!
This is done through a SVG mod that at this time is still quite simple with the correct tools.
Forum member Krazer has uploaded a pdf tutorial on how to set up and start your own modified lobby with 9999 XP kills so that you can boost your rank to prestige quickly.
This guide applies to both XBOX 360 and PS3 versions of the game with some small differences between the different platforms.
Open the PDF file and click on your appropriate console to download the needed tools for the patching step.
Earlier the week the US retailer Kmart put the XBox version of Modern Warfare 3 on the shelves almost a week early. While the store quickly realized its mistake it wasn’t quick enough as word spread quickly. First signs were copy’s appearing on eBay with auctions popping up and getting taken down just as quick. One desperate person is reported to have payed $1,725 to play the game a couple of days early.
Some turned their attention to the game itself and its thanks to them we have the first MW3 Glitch video released.
All credit to the original uploader check it out to see some safe spots where you can not die and other good spots found so far. Some of these spots are quite hard to get to as you will need to be of a decent standard of Strafe jumping
