New iphone 4 4.2.1

[Roadkill#IM]

Hey all
Just brought myself an iPhone 4 from the store. However it has 4.2.1 already installed on it, Is there anyway to jailbreak 4.2.1 yet? if not is there anyway to downgrade it as it hasnt had any other versions on it?
thanks in advance

Do a quick search and you are going to find that you can only do a tethered JB right now. You're in the same boat as me. I lost my JB after I had my phone replaced. Sadly the best option for me is to wait until the next untethered JB.

The tethered jailbreak isnt really that bad.

I agree, I am teethered and don't see any problems. The iPhone 4 battery is so good for me it never dies before the end of day, and I think I use it alot. When ever I install programs from cydia, they only want to restart the springboard not reboot the phone, so I don't see a problem with teethered either.
