Ho to all, I'm very new at Iphone World, despite the fact I own an MBP. After reading several threads I still remain in doubt, Is it possible to jailbreak the IOS 4.2.1? if so how? going to the site mentioned on the sticky thread? that says 4.0.1 needed ....but after a new release the jailbreak is gone right. My I4 is unlocked and I only need to SSH to him, need to try to change some things, like the 'tones' used for incoming messages (Email, SMS). Also somehow it says that is as almost 60 GB but only gives me 32 GB, is the IOS 4 so BIG?!? Best regards to u all, and season greetings.
