Will installing cyanogenmod7 on my Samsung Vibrant require me to wipe my phone first? I'm interested in putting CyanogenMod on my Samsung Vibrant (Galaxy S).  The FAQ on Cyanogenmod says:


  Q: Do I have to wipe my data before I install CyanogenMod? 
  
  A: Short answer: Maybe. Long answer: Maybe.


I understand there's a possibility if something goes wrong that I might have to wipe my phone.  However, in the Vibrant instructions right after booting into ClockworkMod Recovery it says to "wipe data/factory reset" and "wipe cache partition".  That seems to me to indicate that a factory reset is required, which I would think would wipe out everything on my phone.

Is it just that the Vibrant's instruction require a reset or am I not understanding something?  Thanks!
In my experience, yes.  I tried without wiping and CM7 failed to boot.
