do I need to jb my 4.2.1 before save shsh? i have no time, i guess=)

now, will the dev-team release unlock for 4.1 or 4.2?

sorry for stupid questions, but i m more than a newbie on it.

no i didnt.

I bought an Iphone with ios 4.1 baseband 02.10.04, and today, accidentaly upgraded it to 4.2.1 via Itunes. I didn't save my shsh file. I was waiting for unlock and to use it with my own sim card. will I be able to unlock it anyway?

no hope?
