How to fix some mysterious problems.

Hi all, I just jailbroke my iphone 4 4.2.1 using greenpoison rc5. Everything seemed to work fine, the phone boots up with the greenpoison logo but gets stuck at the activation screen where it asks for a valid sim. I know there is no unlock for this version yet but I can't even go to the home screen and use the damn phone as at least an ipod!

I tried using the phone book sim card which used to work before but obviously does not work with 4.2!

Please help!

Don't forget to use SAM to deactivate hactivation and reactivate using SAM to increase battery life!!

Use redsnow0.9.6 rc 8 and install cydia . This will hacktivate and install cydia

Hey thanks for your response! This may be a stupid question but would this (hacktivation using rc8)upgrade my baseband? Also, if hacktivated, can I use any sim/carier?

Eagerly waiting for your response!

The unlock should be out when 4.3 is released so sometime in march

You can use Sn0wbreeze to maintain your unlock? This will give you a custom firmware! (Released today)

That only works if your baseband is an ulockable version if you have a locked baseband it won't do anything
