In order to open my sim lock i have to preserve my baseband? But if the jb is out and it doesn't support 5.0 then only i do the upgrade?
Okay. Thanks for the advise Azraeil.

Yes, you are in a tricky situation. How are you using it now by the way?
Whatever it is, just connect your 4s to TinyUmbrella and save the SHSH for 5.0.1 while Apple is still signing it. Maybe the dev team will find a way to use the SHSH in the future.
You don't need to upgrade to 5.0.1 to save the SHSH

How to know whether the iphone is simlocked?
If you have Cydia installed and you have ultrasn0w as a tweak, then your iPhone is sim locked.
If you cannot use any other simcard other than the AT&T or etc etc.
All iPhone sold by Maxis/Digi/Celcom and Apple store Malaysia is sim free
