I remember hearing about how i could not upgrade my old 3GS to the previous jailbreak of 4.0 because i used spirit which would not be used with pwnage tool. Can i use jailbreak me safely? Thanks.

more details: I had jailbroken at 3.1.3 i think the FW befor 4.0 was, it was JB and then i upgraded to 4.0 now its running stock 4.0 and i want to jailbreak it for my brother who is now using it. Is it safe? I Don't want to brick my old/his new phone. Thaks
