You can go to 4.2.1 right now, but when Apple release 4.3 (11th) they will eventually stop you from restoring or going to 4.2.1 but not signing it and force you to go to 4.3, you can however grab your 4.2.1 shsh's right now and then you can restore/go to 4.2.1 even when Apple stop signing it.

Download TinyUmbrella for your OS, connect your iphone and click on 'save shsh', this will save a copy of them on Cydia servers and on your hard drive. No need to be jailbroken to do this.

You need to be running 4.2.1 to use Greenpois0n, an update via itunes will also update the baseband to 3.10.xx but they might not be an issue for you anyway.

Do you have your 4.2.1 shsh's?

i am still on 4.1 and haven't done anything (JB/upgrade) yet.

hi Ven, can you also please advice if the GP6 includes the unlocking of device to use with multiple sims. Also, is there any other JB software that only unlocks the device for use of different sim other than JB the whole device.

None of the jailbreak tools unlock, what they do is install Cydia on your idevice, from where you can install Ultrasn0w for the unklock, but your current 2.10.xx baseband or the 3.10.xx baseband of 4.2.1, can't currently be unlocked. An Ultrasn0w update is coming for the iphone4 sometime after the release of 4.3

thanks for the advice. please do advice will this include the unlocking of the device as well?

(08 Mar '11, 04:31) ProphecyInsane ProphecyInsane's gravatar image

limera1n does not unlock, you need to wait for the next version of Ultrasn0w to unlock your baseband. Expected 1 to 2 weeks from iOS4.3 public release.
