pwning without building ipsw

hi there
after building ipsw file successfuly i have to close winpwn to resume another time..

how can i bypass rebuilding ipsw in winpwn 2.5 and go straight to pwning itunes?

as long as you have save the custom ipsw file then it can be re-use anytime.
Just make sure that you remember to run ipwner and select the custom firmware one time.

With the custom ipsw in hand, all you need is use iTunes to restore it to phone.

or u can use quickpwn
