Hey guys :)

i have the firmware version 4.1 on my iphone 4 atm. i jailbreaked the iphone with limera1n.

now i wanted to update to 4.2.1 and jailbreak the phone with the new greenpois0n

my question is: can i use greenpoison although i have limera1n installed? or do i have to restore my phone?

The limera1n exploit is the same one used by greenpois0n, so it may be possible to just update and run greenpois0n over it.

If you are currently jailbroken on 4.1, however, your best bet is to perform a restore to be certain that greenpois0n will work correctly, yes.

Just a warning, too, upgrading to 4.2.1 will upgrade your baseband to 03.10.01 unless you use TinyUmbrella to preserve your baseband. (Follow these steps if you rely on an unlock, or would like to unlock later)
