How can I jailbreak iOS 4.2.1 (unthethered) if you do not have older SHSH?

Currently I'm looking for this only for my iPad WiFi, so no baseband.

If there are not solutions yet, do not post anything.

Greenpois0n rc5 Has been released and can do an untethered jailbreak on 4.2.1 without older SHSH blobs.

Thanks for the effort but this method requires SHSH from 4.2 beta3, somthing that most people do not have and will never have. – sorin Jan 16 '11 at 15:30
just google limera1n then -> latest version should really work – tekknolagi Jan 17 '11 at 0:46
Doesn't support 4.2.1. There is no way to do it without the 4.2b3 shsh blobs yet. It's speculated that greenpois0n RC5 will be able to on Feb 10th. – MPT Feb 5 '11 at 0:59
It does support 4.2.1! – tekknolagi Feb 5 '11 at 5:21 WORKS! – tekknolagi Feb 9 '11 at 4:20
