Hi All.
Apologies for re-posting this, but I did not get a definative answer and after having to replace my 3g iPhone (Dropped it cracked the screen

) I am a little more cautious about things now.
I have a 1st Gen 16gb iPhone currently unlocked and jailbroken running on 1.1.4(ZiPhone'd) I run Windows Vista (For my shame

)
I have passed it on to the wife who wants to add apps from the App Store, so needs an upgrade.
She is on an O2 (UK) pay as you go sim.
How do I get it from 1.1.4 to 2.2 and retain the unlock and jailbroken state, I downloaded the Custom 2.2 and Quickpwn, but it would not let me do anything as I was on 1.1.4.
Not bothered by loosing apps or stuff.
Am I correct in thinking I:
- Do a complete restore (Hard Reset)
- Connect to iTunes and download and update to 2.2
- Use Quickpwn or Winpwn with a custom IPSW of 2.2 and run through that
- ???

Thanks again for any help.
