it is if you have your sd card formatted for apps2sd. i am assuming you do not and as such you don't need to wipe it.

Well the reason i ask is because i wanna upgrade my rom from fresh .3 to .5.3 and the instructions say to wipe sd:ext. So should I be good? (I already backed up via Titanium Backup)
