Go to settings, options, sensitivity, 10(INSANE) then just spin like usual but it is faster.
Boost. Or do challenges :)
You use the sleight of hand perk.

Play a lot of Search and Destroy it is by far the easiest way to level up.
It depends on your playing style. Call of Duty: Modern Warfare 3 has fast, arcade style action while Battlefield 3 focuses much more strongly on tactics and class roles.From reviewsCall of Duty: Modern Warfare 3 received an average score of 88/100 from critics, and a user score of 3.2/10.Battlefield 3 received an average score of 84/100 from critics, and a user score of 7.8/10.
It depends mostly on your taste. If you want more fast-paced action, I suggest CoD, but if you're more into gorey battles and brutal fights, Gears of War is the way to go.
The answer really depends on what you want/like most. CoDMW3 is a more close quarters game and it is also more fast paced. BF3 is more big maps, drivable vehicles, etc.

It depends on your type of game style call of duty modern warfare 2 is fast any many people play it day and night and it has real guns,perks, customization for your guns,and a ranking system that gives you access to more guns so you decide.Did i mention the kill streak system that helps you gain more points.
you do all of the challenges really fast
No modern warfare 2 can not be played on wildfire the software on any smart phone is to small and not a fast proseccer
Now if u want to level up really fast you need to get 12 people and get 2 party's going and riot shield boost in search and destroy but if u don't boost the best way is headquarters
