This is not the case, Unlocking that you need to jailbreak in order to download the app called Ultrasn0w that is used to unlock your device, now unlocking will enable you to put any micro sim world wide and it will still work..
Based on the OP statement
Do I need to unlock before jailbreaking?
can someone provide a basic outline of the steps one should take leading up to jailbreaking? i see that i need to save blobs and backup my phone in itunes prior to running any jb software....i would like to really study up on the matter and need some guidance...thanks!
Blobs are not used at all for jailbreaking. Blobs are only used for installing/creating custom firmware. This is one of the more comprehensive FAQ guides to jailbreaking in general. I'd focus more on the "Jailbreaking Guides and Definitions" section. For how-to picture guides on how to jailbreak on specific iOS using specific tools, you can view them here. If a guide is not listed there, then it's not possible.
