Just receive my Maxis Iphone 3GS on 3.0.1, ready for JB but was lucky that i came to this thread to double confirm on the process.
from Page 1 and all useful info provided by kind forumers, can i summarized as follows for my unlocked Maxis Iphone 3GS JB:-
1. since the OS is 3.0.1, i dun hv to restore nor update the firmware vide Itunes verion 8 and above , just use Redsn0w 0.8 to JB, choose IPSW 3.0 instead of 3.01.
2. after JB, go direct to Cydia, run Cydia to enable the store of ECID in order to "secure" any future restore/downgrading and JB process since Itunes will only update firmware to 3.1 which currently cant be JB.
Please correct me if i am wrong, just putting what i understand into simple language
Thanks

Pls backup your ECID certificate to Cydia, this is very important.. Don't upgrade to 3.1 ELSE u will NEVER able to JB again.... JB with 3.0 or 3.01 should be fine.. Pls refer to page 1 of this thread for JB to 3.01..
may i know how to backup ECID cert to Cydia pls and do i need to do it after JB my 3GS OS 3.0.1.....Thank you!!!
Ok....Got it after upgrading sources for Cydia, just click "make my life easier", and message on my cydia now- "this device has a pending TSS request"
Oh God, Hope i hv got things right....
