I was going to try a new ROM today, but since my last 2.2 update returned an "error" about not having an app2sd partition (and my SD card is getting somewhat "junky" anyway), I was thinking of just wiping the entire contents and reformatting prior to flashing. I made a mirror copy of my current SD contents to my computer (just in case), but I'm not sure if reformatting the SD is a bad idea. I'm also not sure at which point during the entire re-flashing process I should perform the reformat. Can anyone shed their opinion on if and when to do something like this? Thanks.
