How to jailbreak iPad2 3G 4.3.5? I just bought a new (refurbished) iPad2 3G, and it came with 4.3.5.

It seems I can't jailbreak it because:


There's no jailbreak for 4.3.5
There's no untethered jailbreak yet for 5.1.1
I can't change the firmware to any other version because the signing windows have closed and I don't have any SHSH blobs saved


Am I right? Thanks.
Yeah, I think you may have missed your window.
It seems that a 5.1.1 jailbreak is not too far away (if the jailbreak rumour mill is to be believed), so you might just have to wait it out for that.
