i have a 3g, with 2.0.2 that I jailbroke last summer. I haven't updated the phone since then, and now I'm thinking about updating the phone to the latest 2.2.1 then jailbreaking again etc. I was wondering what I need to do, I guess I need to restore the phone (is this safe) then go from there? Thanks in advance for the help
If you need to unlock,1st upgrade to 2.2&then make sure your baseband is 02.28.00.Then use pwnage tool 2.2.5 with custom fw 2.2.1 on a mac to preserve your baseband & yellowSnow to unlock.
If you don't need to unlock,just use quickpwn on your windows.
