I was given an iPad 1st gen with IOS 4.3 a while back. I've used it a bit and added things like Audio.com books, some songs, some apps, etc. Now I find I need IOS 6 to get some newer apps. How do I upgrade from 4.3 to 6 without losing any of myiPad settings or apps/audio books/etc? With 4.3 I can not use iCloud for backups? I'm concerned that if I simply try to go from 4.3 to 6 that I'll end up with an iPad that won't work, or that I'll lose all my settings and apps and then not know how to fix things. I grew up using PCs and am a novice with the iPad.
