Hi, this is my iphone details. With the following:
-Serial Number: 88946Dxxxxx
-Model: MC134MY
-Modem Firmware 05.12.01
-Firmware 3.1.3
-iPhone 3Gs official maxis set
Just want to ask a few things.
1)Modem Firmware = baseband?
- If yes, baseband got anything to do with jailbreaking?
2) If want to jailbreak ONLY, need to see what baseband is it first or just see the FW or need to see both?
3) Is baseband is only relevant for unlockers & non official iphone set?
4) Can jailbreak my iphone with the current details I provide above using Pwnage tool or Snowbreeze?
By the way, a LYN forumer posted this link to downgrade 3.1.3 to 3.1.2 on baseband 5.11.07 3Gs.
Anyone tried that?
Thanks all for help in advance

1) firmware is firmware.. baseband is different thing.. baseband is big relate to JB..
2) see both lo.
3) of course yes.. baseband for official unlock after upgrade still can call but locked = bye bye.. cant call wor.
4) cannot de.. bcos u update to latest baseband 5.12.01.. but for official u still can unlock but not JB..
actually baseband is most important.. firmware i can go up and down but baseband if u forget to save ur baseband in SHSH then u cant downgrade at the end..
