Jailbreak help please! :)

[chiee]

First of all - I have no clue. At all. So please ignore any stupid question that might come, and all help is much much appreciated!!

I have an iPhone 3Gs, and had it jailbroken with spirit last year (got help with that btw), but after I had to restore my iPhone in iTunes just recently that jailbreak is obviously gone..

I want to jailbreak it again with a non tethered jailbreak preferably, so can anyone tell me how to, and which jailbreak to use?

The 'about' in my iPhone says as follows:
version: 4.2.1 (8C148a)
modem firmware: 05.15.04


thanks !
chiee

Hope unlock wasn't important, because u updated ur baseband and its can't be unlock for now!!

Muhahahahahahah! but yeah, if you need an unlock, ah well wait, ipad BB isn't worth it

Unlocked.. as in being able to use whatever phone carrier I want right?

Then my iPhone's already unlocked.

This won't change if I jailbreak it would it?!?

Yes, if you see your carrier now, you are atleast unlock to your carrier. If you have a factory unlock, you will be able to use any GSM sim card on this iphone.
There is another unlock called software unnlocked, it uses a tool to unlock your Baseband but your current bb cannot be unlocked by the current tool.
