okay i try like 3 roms, my first one was appex,2nd gummyjar, 3rd liberty but after i try 2nd & 3rd i went back to apex but my qustion is if when i installed the roms over the rooms (appex-->gummyjar--->liberty--->appex) automatically the other roms deleted? or still on my memory? and if they're on my memory how i can delete?
In my opinion, I think it's best to wipe before flashing to another ROM (unless ur upgrading from 1 rom to the next within the same series - i.e.: CM6.1 -> CM6.1.1)
That's just a safe measure just in case there's old code and what not lingering that may mess with what you're currently running.
