Just to clarify before I go and jump off the deep end I just want to confirm that i can jailbreak my iphone 3G (with 2.2.1 firmware) then once yellowsn0w (or whoever) releases an unlock for it further down the line I can then use that to unlock. I just became confused thinking that I would NEVER be able to unlock if I jailbroke it...if someone could clarify this for me it would be great!....sorry but I need these things explained in pigeon English before I go off and cock it all up! cheers!
