The dev team just updated redsn0w to version 0.9.6b4, which will jailbreak ios 4.2.1. as we explained yesterday, thanks to a combination of pwnage2 exploit, the arm7_go exploit, 24kpwn, and limera1n, you will get an untethered jailbreak for iphone 3g, older iphone 3gs, and non-mc ipod touch 2g.. Starting with fw 4.2.1 if you have 06.15 on your iphone you won’t ever be able to restore to stock firmware (it will fail). you’ll need to only restore to custom ipsws (then again, if you’re unlocker you should already be doing that)..
