H1B petition validity to transfer to other employer.. Pls Help


I applied for H1B in 2008 through one X employer and the petition got approved and stamped on the same year. I haven't used that H1B since they cancelled my H1B visa stamped in my passport. I have the receipt number and hard copy of petition. when they cancelled my H1B is that mean my petition gets cancelled and i can't use it later for other employer to transfer it.

is it possible to use the same petition to transfer by some other employer ? Will this come i under new Cap/cap excemption ? I am trying to find a employer to transfer and use it. 


Another employer can file for cap-exempt petition for you even after it was canceled. They can submit copy of previously approved petition to show that you have already made through the cap.
