Stupidly Updated to 4.2.1, and Now Need Clarification

Ok, I won my iPad in a raffle two days ago and immediately plugged it into my MacBook pro, and was prompted to update it 4.2.1. Without thinking i agreed and it updated....

Today, I was going to jailbreak it until I read up on the topic and noticed that the SHSH blobs from 4.1 were necessary for any jailbreak, including the upcoming untethered version. I then proceeded to yell profanities in my room for about an hour until I cooled down.

To get to the point, here's my main question:

Will I ever be able to jailbreak my iPad untethered, even though I do not have the SHSH blobs from 4.1?
