I am confused about the whole wiping the cache and data. I don't know exactly what cache and data are and that's why I'm confused. Do u have to wipe all data and cache before u switch roms, if not what happens? I am afraid of losing all of my apps and contacts even tho my gmail will restore my contacts how do I know if it has the contacts saved and how would I get my apps back? One more thing, do u have to make more than one backup if u already have one that u r happy with? Thanks for your help. Can anyone help me out with this? I'm waitin to upgrade to smoked glass 5.0.1 until I learn how upgrade to smoked glass 5.0.1 until I learn how to do it correctly so I would really appriciate it if someone could take a minute and help me out. Thanks.
