Now that greenpoison is out to untether 4.2.1 on the 3gs, can i unlock the 3gs as well now? My friend has one he wants to sell to another friend on t-mobile. I recently did a 3g on a 4.2.1 but that was easy. Everything up until now on the 3gs just looked grim, but now theres this. The 3gs my friend has said it wasnt unlockable (like 2 weeks ago before the untethered JB came out) using f0recast (new bootrom i guess). If greenpoison could install the ipad baseband would that allow the phone to be unlocked using UltraSnow? Does greenpoison even have the option to install the ipad baseband to allow this?
