ok so how do i go about doing this? I am gonna buy a 1st gen iphone for 100 bucks from a friend. it isnt jailbroken or anything. what do i have to do to get it to 3.1.2 unlocked? i know i can JB using Blackra1n but geohot said that blacksn0w wont work for 2g and to use something called bootneuter??? does that work on fw 3.1 or do i have to downgrade to 2.0 first? im so confused lol. i would really appreciate any help. thanks!
