for those who have "no service" after downgrading from 7.1.2 to 6.1.3 in iPhone 4 , the solution is :
1- in "flash and jb" pane
2- go " advanced"
3- and then click "deactivate".
the iPhone will deactivated and after that comes up and wants u to "activate your iPhone" (iPhone first wizard for activation"
connect it to wifi and press activate, then u will see the signal bar comes !!!
Finish
