So I have a 2G iPod touch. A few days ago I upgraded from 2.2.1 jailbreak to 3.1.2. Everything is fine; I still have my photos and my apps. But I only have a few megabytes left. The "other" is taking up 4.5 GB if my space. So I looked it up on google and everywhere I go it says I have to restore. So I was wondering, since I'm planning on jailbreaking it using blackra1n, will that get rid of all the "other" files? Also, will jailbreaking it get rod of all my songs, apps, and photos?
