Updating iphone 2g to 2 2
Find my i Phone (FMI) is a function that stops other people from using your i Phone 2G when it gets lost or stolen.
In order to remove the FMI blockade you need to enter an e-mail adress and password used by the owner of this device.
Due to the hassle of tethered booting, I do not recommend most users jailbreak i OS 4.2.1 using redsn0w, instead you should wait for a new version of Pwnage Tool or limera1n/greenpois0n, both of which are due shortly and they will be untethered jailbreaks. Remember, if you have any intention on ever unlocking your i Phone, do not use redsn0w and do not upgrade to i OS 4.2.1 yet.
Instead, save your SSH blobs from i OS 4.1 and wait for further unlock instructions.
