Iphone: Quickpwn says that it can only jailbreak devices >= 2.0, but i have 2.2

installed on my iphone? Basically i want to unlock and jailbreak my iphone simultaneously, using quickpwn.

When i bought it, it was already jailbroken, but to use quickpwn you have to do both

I have firmware 2.2 installed on my iphone.
When i plug it into quickpwn, it says "this version can only jailbreak devices version >= 2.0", whereas i have the 2.2 software installed on my iphone.

What do I do????????????

Thanks in advance!!!!!!!1
