Through this song the same chords are played over again( F, Am, Dm & Bb)
In the background you would here this:

e--13---12---13---10-----|
b--13---13---15---11-----|
g--14---14---14---10-----|
d------------------------|
a------------------------|
E------------------------|

During B.o.B's part there is a little riff that goes like this:

       Slide
e--13--15-17--15-13  -12----15--11  -10--13--10  -10---------------|
b--13--------------  -13----13----  -10--10----  -11--------11--11-|
g--14--15-17--15-14  -14----14----  -10--10----  -10--Slide-10--10-|
d------------------  -------------  -----------  -----10-12---12---|
a------------------  -------------  -----------  ------------------|
E------------------  -------------  -----------  ------------------|

Also while playing throught this song it sounds really good making up solos using the F 
Major Pentatonic shown below.

e---------------------------10-13-|
b---------------------10-13-------|
g---------------10-12-------------|
d---------10-12-------------------|
a---10-12-------------------------|
E-13------------------------------|

I hope this helps.
