When I go to do a nandroid backup, it give me a list of selectable items. What do I need to select? It defaults to a few things, but wimax is not one of them. I figured that's a no-brainer that I need to make sure to select...is there anything else? I figured that he would probably default the important stuff, but I just want to make 100% sure that I catch everything I would need for a restore if I need to down the road. I'm using the new version...2.3 by the way. My options are (the ones with an X are marked by default): [x]boot [x]system [x]data cache recovery wimax sd-ext .android_secure It says that sd-ext and .android_secure backups require lots of SD card space...not sure if they're essential.
