Redsn0w jb for 4.3.1 ruined my 3GS (Maxis), via Win XP x86, managed to jailbreak but can't detect telco or no signal just like an iPod Touch, after full restore even worst, can't unlock with my SIM pin code, can someone enlighten me how? Thanks

Nope,why? You managed to do so?

what I mean is do you manage to jailbreak your 3GS which iOS4.3.1 with RedSn0w? because I screwed once, and I brought to Maxis Centre to restore it, so I couldn't afford to make it lock again, i

kk, thanks, i do appreciate for your assistance. because when i brought to maxis centre few days back, they somehow refuse to help and stated that my warranty is over. but luckily they managed to unlock it again, the office told me that my 3GS hanged, would it be possible from a failure jailbreak or recovery? the most curious part is they managed to make it unlock within few minutes? i was wondering what have they done? is hard reset? just in case if i screwed up the process, i can solve by myself rather than panicking. i shall give it another try later on. thanks again.
