iPhone 4.2 Untethered JB/Unlock

[scoobydrew813]

I have an iP4 that is on a preserved old 1.59 baseband (runnig 4.1), and I was wondering if an untethered jailbreak/unlock 4.2 solution has been released for me to use on my iPhone. Thanks in advance

If you need unlock, i suggest you stay at 4.1 for now. You can only get untethered jailbreak if you have 4.2b3 blob and you must use a Mac. You have to go with unofficial pwnage tools to preserve your baseband but anything can go wrong and you will end up with an itouch 4.

Exactly what he said. If you don't have the 4.2b3 blobs already saved then there is no way to get them anymore.

As for preserving your unlock on 4.2.1, your best bet would be the pwnage tool as is it will not update your baseband. There is another way but it is alot more risky then pwnage tool and you would have to be at a lower firmware like 4.1.

Use at your own risk!
