i haven't been into iphone or ipod touch JB for awhile ever since i traded them both in. But recently my father has been planning on getting a iPhone 3G and i have a few questions i wish to clarify. -When you jailbreak the iphone, you essentially 'unlock' the iphone to use any GSM and carrier, right? Someone told my dad they are 2 different things, and from what i knew before, when you jailbreak it, you unlock it, too. -Is the latest jailbreak-able firmware for Iphone 3G 3.1.2? -If so, which software is recommended for this? I remember using Blackra1n for my ipod and Winpwn for iphone, but im not sure if they have been keeping it up on jailbreaking. -Lastly, is jailbreaking the 3G an 3GS one and the same? If not, whats different about them?
